The SCJP Handbook

With at least a dozen books on SCJP in the market, a question naturally arises is to why add one more? The Java certification assesses the conceptual knowledge and is not similar to academic or theoretical examinations. Hence purely academic approach may not work well for the exam. Therefore while following the SCJP syllabus, sufficient efforts must be put in to get true understanding of essential java concepts. There are many excellent books on SCJP and they are good enough for readers who know Java quite well. However they may be bit confusing for Java beginners. Since SCJP exam is particularly popular among Java beginners, this is an important issue. The SCJP Handbook tries to be different- While focusing on SCJP objectives—the assessment of important core Java concepts—it goes one step further—to discuss the concepts themselves.
When I started preparing for SCJP I knew only as much Java as needed for my work. Preparation for SCJP gave me an opportunity to experiment with several other interesting aspects of Java (threads for instance) and to learn “Java-as-a-language” from scratch. But while doing so I had gone through several books to truly get the picture of many Java concepts. It made me think to write a book on SCJP. I wrote this book because this was the book that I wanted to read when I started my SCJP preparation. I hope to make this book a one-stop-solution for SCJP.

Oracle PL/SQL Programming Second Edition

What, specifically, will this book help you do?
Take full advantage of PL/SQL. The reference manuals may describe all the features of the PL/SQL language, but they don't tell you how to apply the technology. In fact, in some cases, you'll be lucky to even understand how to use a given feature after you've made your way through the railroad diagrams. Books and training courses tend to cover the same standard topics in the same limited way. In this book, we'll venture beyond to the edges of the language, to the nonstandard ways in which a particular feature can be tweaked to achieve a desired result.
Use PL/SQL to solve your problems. You don't spend your days and nights writing PL/SQL modules so that you can rise to a higher plane of existence. You use PL/SQL to solve problems for your company or your customers. In this book, I try hard to help you tackle real-world problems, the kinds of issues developers face on a daily basis (at least those problems that can be solved with mere software). To do this, I've packed the book with examples -- not just small code fragments, but complete application components you can apply immediately to your own situations. There is a good deal of code in the book itself, and much more on the disk that accompanies the book. In this book I guide you through the analytical process used to come up with a solution. In this way I hope you'll see, in the most concrete terms, how to apply PL/SQL features and undocumented applications of those features to a particular situation.
Write efficient, maintainable code. PL/SQL and the rest of the Oracle products offer the potential for incredible development productivity. If you aren't careful, however, this rapid development capability will simply let you dig yourself into a deeper, darker hole than you've ever found yourself in before. I would consider this book a failure if it only ended up helping programmers write more code in less time than ever before. I want to help you develop the skills and techniques that give you the time to build modules which readily adapt to change and are easily understood and maintained. I want to teach you to use comprehensive strategies and code architectures which allow you to apply PL/SQL in powerful, general ways to many of the problems you will face.

Oracle PL/SQL Programming - Guide to Oracle8i Features

2700 pages and still writing! Sometimes I feel like the Energizer Bunny of PL/SQL. But Oracle keeps the features coming, and after all these years, I'm still enthusiastic about what PL/SQL can do to improve the quality of life for developers. Even with the coming of Java(TM) in Oracle8i, I believe strongly that the future is bright for PL/SQL developers.
This short book is something of a departure for me -- those of you who have read my larger tomes may wonder if I've found a ghostwriter! Now that Oracle8i is here, it's my intention to update Oracle PL/SQL Programming (now in its second edition) to cover the new version of the Oracle database. Along with developing a third edition of that book (with my coauthor Bill Pribyl), I'm taking a critical look at all of my books to make sure that the O'Reilly & Associates PL/SQL series offers a comprehensive resource for PL/SQL developers.
For now, though, PL/SQL developers need current and useful information about the latest PL/SQL features; there are a lot of them, and some represent major changes in the language. This small book is intended to get you started on understanding these features and using them to best advantage.
For many people, the big news about Oracle8i is Java, and the big question for many PL/SQL developers is how (and whether) to use Java in conjunction with PL/SQL. Chapter 9, Calling Java from PL/SQL, is a roadmap showing PL/SQL developers how to employ Java right now. It doesn't attempt to teach you the basics of Java -- there are many other books that serve that purpose -- but it does teach you how to access Java from within PL/SQL.

Oracle Built-in Packages

After publishing more than 1,600 pages on Oracle PL /SQL in two previous books, I marvel at the existence now of this third book covering yet other aspects of the PL /SQL language. I can still remember quite distinctly a moment in September, 1994, when I embarked on writing the first draft of Oracle PL /SQL Programming and wondered: are there really 400 pages worth of material on that much-used and often-maligned procedural language from a nonprocedural (SQL) company? If the answer to that question was a resounding "yes" in 1994, then the answer is a deafening roar today!
Maybe PL /SQL isn't the answer to every object-oriented programmer's deepest desires. Maybe developers are badly in need of -- and unreservedly deserve -- better tools with which to write, debug, and reuse PL /SQL programs. Maybe PL /SQL isn't perfect, but the reality is that hundreds of thousands of people around the world work (and struggle) with PL /SQL on a daily basis. We all need as much information as possible about how we can make the best possible use of Oracle PL /SQL.
And that is the objective of Oracle Built-in Packages. If you are going to build complex applications using PL /SQL, you will not succeed unless you learn about and figure out how to utilize many of the packages described in this book. Packages are the method of choice for Oracle and third parties like RevealNet, Inc., to extend the base PL /SQL language, to improve ease of use, and to provide brand-new functionality in the language. Writing PL /SQL code without knowing about or using built-in packages is akin to building an automobile and ignoring the last 20 years of technological advances. The resulting machine will run more slowly, use more gas, and be harder to repair.
Oracle Built-in Packages grew out of Chapter 15 of the first edition of Oracle PL /SQL Programming. When Oracle released Oracle8, it was time to update that book to include the wide-ranging new PL /SQL8 functionality. It was clear from the start that this second edition, if organized like the first, would have been well over 1,500 pages in length -- a totally impractical size for a developer's handbook.
What to do? Based on feedback from developers about Oracle PL /SQL Programming, there was an enormous amount of interest in, and often confusion surrounding, the built-in packages. These Oracle-provided "add-ons" to PL /SQL clearly needed more detailed coverage, more examples, more tips, more of just about everything. My single chapter of 100 pages was woefully inadequate. We made the decision to move that single chapter out of Oracle PL /SQL Programming and expand it into a book all its own. You are holding the result.
I recognized early in the process that I couldn't personally cover all of the Oracle built-in packages discussed in this book. I didn't have the necessary expertise, nor the time to learn, nor the time to write it all. So I sought and received the help of two excellent Oracle technologists: John Beresniewicz and Charles Dye.
Over the past six months, John, Charles, and I have researched the packages provided by Oracle in the database, verified the documentation, uncovered aberrant behavior, and discovered neat tricks. We also made it a priority to construct package-based utilities that you will be able to put to immediate use.
While Oracle Built-in Packages is a collaborative effort, it is also a combination of very individual efforts. As such, you will find differences in coding styles and philosophies. Rather than try to enforce a single standard throughout, I welcomed the variations (as long as all contributed in their own way to a deeper, clearer understanding of the PL /SQL technology). There is rarely a single right way to do anything, and there is an enormous amount we can learn from the different journeys each of us takes to a solution.

Advanced Oracle PL/SQL Programming with Packages

Who would have thought that just one year after the publication of Oracle PL/SQL Programming, a 916-page tome on "everything PL/SQL", I'd end up writing a second book about the PL/SQL language? Although back in September 1995 I wasn't arrogant enough to think that I knew all there was to know about PL/SQL, I also underestimated how much more I had still to learn!
I am firmly of the belief that one never stops learning -- as long as one is open to learning. The area of PL/SQL in which I needed lots more education turned out to be packages. In my first book I explained how to build and use packages. I even provided lots of examples of package construction. But I started to realize that this wasn't enough. Over the past year, I have been designing and developing a set of packages to help me build PL/SQL-based applications. This was a thoroughly selfish effort: I wanted to be as productive as possible, and I wanted to overcome a number of weaknesses -- however transient -- in the PL/SQL language. In the process of writing this software, I learned a good deal about the best ways to build PL/SQL code, especially regarding packages. I also discovered some very interesting techniques that can make packaged software more maintainable, accessible, and easy to use.
As my thinking on the construction of packages crystallized, I began to view all of my packages as a library of code that could be used by any PL/SQL developer. I also realized that I wanted to share the new techniques and lessons I had uncovered. The result? This book and the PL/Vision product.
How often do you find yourself writing a program and simultaneously thinking: somebody must have done this before! You feel certain that you are reinventing the wheel. Worse, if you are sufficiently honest with yourself, you will also admit that someone else has probably spent more time on the problem and has already come up with a better solution than you are likely to develop for your specific application.
Often, you know you should take the time to "genericize" a program so that you can use it again and again in different circumstances. Somehow, however, you never find the time -- and the mental space -- to take your code to that higher level of abstraction.
So you limp along, accepting a relatively low level of productivity and reusing a truly minimal amount of code. You write the same things over and over and simply push aside the feeling that you are wasting your time.
Oracle developers are fortunate to be able to use an advanced, robust language like PL/SQL. PL/SQL developers are, on the other hand, less than fortunate (at least as of September 1996) to find that the supporting environment for PL/SQL is still very immature. Where are the debuggers, the code formatters and generators, the toolboxes of reusable programs and objects? When will we have a powerful editor that knows about PL/SQL syntax and -- more importantly -- the stored code available for execution?
When, you might also ask, will this guy stop complaining? It is acceptable to identify weaknesses. It is constructive to analyze areas for improvement. At some point, however, you have to stop whining and start improving things for yourself. Best yet, keep on whining but engage in self-improvement at the same time!
This book will help you write better packages. It will also show you how to use the "prebuilt" packages of the PL/Vision software product -- my attempt to change the "situation on the ground" for PL/SQL programmers. Finally, I hope that it will, via examination of my source code and the way I separated functional areas in PL/Vision, offer a blueprint for PL/SQL developers to discover how to take full advantage of PL/SQL packages in their day-to-day programming.

Oracle Web Applications PL/SQL Developer's Introduction

The goal of Oracle Web Applications is to help Oracle SQL and PL/SQL developers who have little or no web programming experience to learn to develop useful web applications, using technologies most IS developers can grasp fairly quickly: WebDB, Oracle Application Server (OAS), PL/SQL, HTML, and XML.
In addition, the book introduces several other Oracle8i technologies -- Advanced Queuing (AQ), the Internet File System (iFS), interMedia, InternetLite, and Java(TM) -- and shows how they form a cohesive development framework that addresses the pressing issues of web content management, application development, and application integration. While there have been many changes in Oracle8i, it's still just a database, and there's no need to panic: data is data, whether it comes from the accounts payable system or from the Internet.
This book acknowledges that you're a busy person. Since most of us simply don't have time to read and digest an 800-page book on each individual technology, I've tried to present fundamental elements of the topics you'll use most often in your daily development efforts. This book will get you started and solidly on your way, but it's not, obviously, the ultimate reference. Rather, it is a "Cliff Notes" of Oracle web development -- enough to help you pass the test, but not enough to help you appreciate the finer points. Once you've read the book, however, you'll be ready to delve into the various areas (WebDB, PL/SQL, Java, etc.) more deeply. Your first step on that journey should be to consult the appendix for information on further resources.

Although we don't include every single package and function in this pocket reference, we've included all the built-ins that most PL/SQL developers will ever need to use.

The purpose of this pocket reference is to help PL/SQL users find the syntax of specific built-in headers. It is not a self-contained user guide; basic knowledge of PL/SQL and its built-ins is required. For more information, see the following books:

• Oracle PL/SQL Programming, by Steven Feuerstein and Bill Pribyl (O'Reilly & Associates, Second Edition, 1997).
• Oracle Built-in Packages, by Steven Feuerstein, Charles Dye, and John Beresniewicz (O'Reilly & Associates, 1998).

Getting Started with MySQL

This article is the first in an educational series offered by MySQL AB aimed towards providing the reader with valuable insight into the MySQL database server. Although future articles will delve into some of the more complicated topics surrounding MySQL, including replication, ODBC and optimization, it was thought to be prudent if the first tutorial started, well, at the beginning. Therefore the goal of this article is to thoroughly acquaint the reader with various topics surrounding the basic functioning of MySQL. A synopsis of what is covered is shown in the Table of Contents, listed below. You can go to any topic listed in the Table of Contents simply by clicking on its title.

MySQL 5.1 Reference Manual

This is the Reference Manual for the MySQL Database System, version 5.1, through release 5.1.12-beta. It is not intended for use with older versions of the MySQL software due to the many functional and other differences between MySQL 5.1 and previous versions. If you are using an earlier release of the MySQL software, please refer to the MySQL 5.0 Reference Manual, which covers the 5.0 series of MySQL software releases, or to MySQL 3.23, 4.0, 4.1 Reference Manual, which covers the 3.23, 4.0, and 4.1 series of MySQL software releases. Differences between minor versions of MySQL 5.1 are noted in the present text with reference to release numbers (5.1.x).

Because this manual serves as a reference, it does not provide general instruction on SQL or relational database concepts. It also does not teach you how to use your operating system or command-line interpreter.

The MySQL Database Software is under constant development, and the Reference Manual is updated frequently as well. The most recent version of the manual is available online in searchable form at http://dev.mysql.com/doc/. Other formats also are available there, including HTML, PDF, and Windows CHM versions.........

Database Programming with Perl

Types of databases
There are many different types of databases, including:

• Flat-file text databases
• Associative flat-file databases such as Berkeley DB
• Relational databases
• Object databases
• Network databases
• Hierarchical databases such as LDAP

Relational databases are by far the most useful type commonly available, and this training module focusses largely on them, after looking briefly at flat file text databases.

Concurrency Control and Recovery in Database Systems

For over 20 years, businesses have been moving their data processing activities on-line. Many businesses, such as airlines and banks, are no longer able to function when their on-line computer systems are down. Their on-line databases must be up-to-date and correct at all times.

In part, the requirement for correctness and reliability is the burden of the application programming staff. They write the application programs that perform the business’s basic functions: make a deposit or withdrawal, reserve a seat or purchase a ticket, buy or sell a security, etc. Each of these programs is designed and tested to perform its function correctly. However, even the most carefully implemented application program is vulnerable to certain errors that are beyond its control. These potential errors arise from two sources: concurrency and failures.

Multiprogramming is essential for attaining high performance. Its effect is to allow many programs to interleave their executions. That is, they execute concwrently. When such programs interleave their accesses to the database, they can interfere. Avoiding this interference is called the concurrency control problem.

Data Transfer Strategies

Transferring data between XML documents and relational databases

by Ronald Bourret

In this paper we will discuss strategies for transferring data between XML documents and relational databases according to two mappings (a table-based mapping and an object-based mapping) commonly used to map DTDs to relational databases. Although the discussion largely focuses on the difference between using SAX- and DOM-based tools to transfer data, it also discusses a number of strategies for traversing both the XML and database hierarchies and the tradeoffs among them.

Building a Database-Driven Web Site Using PHP and MySQL

On the Web today, content is king. After you've mastered HTML and learned a few neat tricks in JavaScript and Dynamic HTML, you can probably build a pretty impressive-looking Web site design. But then comes the time to fill that fancy page layout with some real information. Any site that successfully attracts repeat visitors has to have fresh and constantly updated content. In the world of traditional site building, that means HTML files--and lots of 'em.

The problem is that, more often than not, the people providing the content for a site are not the same people handling its design. Oftentimes, the content provider doesn't even know HTML. How, then, is the content to get from the provider onto the Web site? Not every company can afford to staff a full-time Webmaster, and most Webmasters have better things to do than copying Word files into HTML templates anyway........

Introduction to Databases for web developers

Types of Database

These days, when you talk about databases in the wild, you are primarily talking about two types:

• Analytical databases
• Operational databases.

Let's examine each type

Analytic databases (a.k.a. OLAP- On Line Analytical Processing) are primarily static, read-only databases which store archived, historical data used for analysis. For example, a company might store sales records over the last ten years in an analytic database and use that database to analyze marketing strategies in relationship to demographics.

On the web, you will often see analytic databases in the form of inventory catalogs such as the one shown on the previous page from Amazon.com. An inventory catalog analytical database usually holds descriptive information about all available products in the inventory.

Web pages are generated dynamically by querying the list of available products in the inventory against some search parameters. The dynamically-generated page will display the information about each item (such as title, author, ISBN) which is stored in the database.

Data Modeling Techniques for Data Warehousing

This redbook gives detail coverage to the topic of data modeling techniques for data warehousing, within the context of the overall data warehouse development process.

The process of data warehouse modeling, including the steps required before and after the actual modeling step, is discussed. Detailed coverage of modeling techniques is presented in an evolutionary way through a gradual, but well-managed, expansion of the content of the actual data model.

Coverage is also given to other important aspects of data warehousing that affect, or are affected by, the modeling process. These include architecting the warehouse and populating the data warehouse.

Guidelines for selecting a data modeling tool that is appropriate for data warehousing are presented.

Data Mining Desktop Survival Guide

Knowledge leads to wisdom and better understanding. Data mining builds knowledge from information, adding value to the tremendous stores of data that abound today--stores that are ever increasing in size and availability. Emerging from the database community in the late 1980's the discipline of data mining grew quickly to encompass researchers from Machine Learning, High Performance Computing, Visualisation, and Statistics, recognising the growing opportunity to add value to data. Today, this multi-disciplinary effort continues to deliver new techniques and tools for the analysis of very large collections of data. Searching through databases measuring in gigabytes and terabytes data mining delivers discoveries that can change the way an organisation does business. It can enable companies to remain competitive in this modern data rich, knowledge hungry, wisdom scarce world. Data mining delivers knowledge to drive wisdom.

For a long time, Statisticians and more recently Machine Learning researchers, have sought to add value to data by building models from data samples. From a statistics point of view, the aim is generally to build accurate models. From a machine learning point of view, the aim is generally to gain understanding that can be turned into actionable knowledge. Irrespective the models can help better understand the general behaviour of systems and even predict outcomes for new cases.

Statistical and symbolic techniques have often been hamstrung by their computational and memory requirements, leading to long waits for models to be built over very large datasets. Alternatively sampling of the data is required in order to generate models in a reasonable time. Traditionally we might also characterise the statistical approach as apriori hypothesis testing rather than data exploration.

Data mining strives to discover new knowledge (new hypotheses) from data, effectively letting the data speak for itself. Previously unknown patterns in very large databases are searched for, presenting discoveries in a human accessible form.

How Computers Work - Processor and Main Memory

Computers are the most complex machines that have ever been created. Very few people really know how they work. This book will tell you how they work and no technical knowledge is required. It explains the operation of a simple, but fully functional, computer in complete detail. The simple computer described consists mainly of a processor and main memory. Relays, which are explained, are used in the circuitry instead of transistors for simplicity. This book does not cover peripherals like modems, mice, disk drives, or monitors.
Did you ever wonder what a bit, a pixel, a latch, a word (of memory), a data bus, an address bus, a memory, a register, a processor, a timing diagram, a clock (of a processor), an instruction, or machine code is? Though most explanations of how computers work are a lot of analogies or require a background in electrical engineering, this book will tell you precisely what each of them is and how each of them works without requiring any previous knowledge of computers or electronics. However, this book starts out very easy and gets harder as it goes along. You must read the book starting at the first page and not skip around because later topics depend on understanding earlier topics. How far you can get may depend on your background. A junior high school science background should be enough. There is no mathematics required other than simple addition and multiplication. This is a short book, but it must be studied carefully. This means that you will have to read some parts more than once to understand them. Get as far as you can. You will be much more knowledgeable about how computers work when you are done than when you started, even if you are not able to get through the whole text. This is a technical book though it is aimed at a non-technical audience. Though this book takes considerable effort to understand, it is very easy for what it explains. After you have studied this book, if you go back and read it, it will seem simple. Good Luck!

How Computers Work

Includes the basics of digital logical design, computer organization and architecture including assembly language, processor design, memory hierarchies and pipelining. Students examine the detailed construction of a very simple computer. Problem sets use Beta-Sim, a RISC simulator written by Mike Wessler. A higher level view of a modern RISC architecture is studied, using the Patterson and Hennessey introductory text, from both the programmer's point of view and the hardware designer's point of view. The distinction between RISC and CISC architectures is emphasized.

Basic Computing Using Windows

Computers and Peripherals
What is a computer? A computer is a machine that inputs (takes in) facts and information (known as data), and then processes (does something to or with) it. Afterwards it outputs, or displays, the results for you to see. Data is all kinds of information, including, pictures, letters, numbers, and sounds. There are two main parts of computers, hardware and software. Hardware is all of the parts of the computer you can see and touch. Software is the instructions that a computer uses to do what you ask it to. Pieces of software are often called programs.

Many people mistakenly think that where the computer normally displays things is the computer. This is not true. That is the monitor. The computer is usually a box. Also, you may call the whole assembly of all the hardware (the computer and the monitor, for example) the computer.
There are different styles of monitors. One of these is the one already shown. It is called a CRT monitor. It takes more power than the other popular kind, called LCDs. However, CRT monitors work faster, which makes them better for fast games because the movement will blur less. LCDs are thinner than CRTs, but they are more expensive.

Assemblers and Loaders

This book differs from the typical assembler text in that it is not a programming manual, and it is not concerned with any specific assembler language.Instead it concentrates on the design and implementation of assemblers and loaders. It assumes that the reader has some knowledge of computers and programming, and it aims to explain how assemblers and loaders work. Most of the discussion is general, and most of the examples are in a hypothetical, simple, assembler language. Certain examples are in the assembler languages of actual machines, and those are always specified.
This is mostly a professional book, intended for computer professionals in general, and especially for systems programmers.Ho wever, it can be used as a supplementary text in a systems programming or computer organization class at any level.
Chapter 1 introduces the one-pass and two-pass assemblers, discusses other important concepts—such as absolute- and relocatable object files—and describes assembler features such as local labels and multiple location counters. Data structures for implementing the symbol table are discussed in chapter 2.
Chapter 3 presents many directives and discusses their formats, meaning, and implementation.These directives are supported by many actual assemblers and, while not complete, this collection of directives is quite extensive.
The two important topics of macros and conditional assembly are introduced in chapter 4. The treatment of macros is as complete as practically possible. Features of the listing file are outlined, with examples, in chapter 5, while
chapter 6 is a general description of the properties of disassembler, and of three special types of assemblers.Those topics, especially meta-assemblers and high-level assemblers, are of special interest to the advanced reader.They are not new, but even experienced programmers are not always familiar with them.
Chapter 7 covers loaders.There is a very detailed example of the basic operation of a one pass linking loader, followed by features and concepts such as dynamic loading, bootstrap loader, overlays, and others.
Finally, chapter 8 contains a survey of four modern, state of the art, assemblers. Their main characteristics are described, as well as features that distinguish them from their older counterparts.

ARM Assembly Language Programming

By Peter Knaggs and Stephen Welsh
Broadly speaking, you can divide the history of computers into four periods: the mainframe, the mini, the microprocessor, and the modern post-micoprocessor. The Mainframe era was chaterrized by computers that required large buildings and teams of technicians and operators to keep them going. More often than not, both academics and students had little direct contact with the mainframe - you handed a deck of punched cards to an operator and waited for the ouput to appear hours later. During the mainframe era, academics concentrated on languages and compilers, algorithms, and operating systems.
The minicomputer era put computers in the hands of students and academics, because university departments could now buy their own minis. As minicomputers were not as complex as mainframes and because students could get direct hands-on experience, many departments of computer science and electronic engineering taught students how to program in the native language of the computer - assembly language. In those days, the mid 1970s, assembly language programming was used to teach both the control of I/O devices, and the writing of programs. The explosion of computer software had not taken place, and if you wanted software you had to write it yourself.
The late 1970s saw the introduction of the Microprocessor. For the first time, each student was able to access a real computer. Unfortunately, microprocessors appeared before the introduction of low-cost memory (both primary and secondary). Students had to program microprocessors in assembly langauge because the only storage mechanicsm was often a ROM with just enough capacity to hold a simple single pass assembler.
The advent of the low-cost microprocessor system ensured that virtually every student took a course on assembly language. Even today, most courses in computer science include a module on computer architecture and organization, and teaching students to write programs in assembly language forces them to understand the computer's architecture. However, some computer scientist who had been educated during the mainframe era were unhappy with the microprocessor, because they felt that the 8 bit microprocessor was a retrograde step - its architecture was far more primitive that the mainframes they had studied in the 1960s....

Complete WAP Security

The Wireless Application Protocol (WAP) is a leading technology for companies trying to unlock the value of the Mobile Internet.

Certicom products and services provide complete WAP security solutions today for all of those players involved in bringing the Internet to the mobile end-user — including content providers, equipment manufacturers, network operators, application service providers and enterprises.

WAP
The WAP (Wireless Application Protocol) is a suite of specifications that enable wireless Internet applications; these specifications can be found at http://www.wapforum.org). WAP provides the framework to enable targeted Web access, mobile e-commerce, corporate intranet access, and other advanced services to digital wireless devices, including mobile phones, PDAs, two-way pagers, and other wireless devices. The suite of WAP specifications allows manufacturers, network operators, content providers and application developers to offer compatible products and services that work across varying types of digital devices and networks. Even for companies wary of WAP, individual elements of the WAP standards can prove useful by providing industry-standard wireless protocols and data formats.
The WAP architecture is based on the realization that for the near future, networks and client devices (e.g., mobile phones) will have limited capabilities. The networks will have bandwidth and latency limitations, and client devices will have limited processing, memory, power, display and user interaction capabilities. Therefore, Internet protocols cannot be processed as is; an adaptation for wireless environments is required. The entire suite of WAP specifications are derived from equivalent IETF specifications used on the Internet, modified for use within the limited capabilities in the wireless world.
Furthermore, the WAP model introduces a Gateway that translates between WAP and Internet protocols. This Gateway is typically located at the site of the mobile operator, although sometimes it may be run by an application service provider or enterprise.

A Comprehensive Guide to Virtual Private Networks, Volume II: IBM Nways Router Solutions

The Internet nowadays is not only a popular vehicle to retrieve and exchange information in traditional ways, such as e-mail, file transfer and Web surfing. It is being used more and more by companies to replace their existing telecommunications infrastructure with virtual private networks by implementing secure IP tunnels across the Internet between corporate sites as well as to business partners and remote locations.

This updated redbook includes the IPSec enhancements provided by Version 3.3 of the IBM Nways Multiprotocol Routing Services (MRS), Nways Multiprotocol Access Services (MAS) and Access Integration Services (AIS) that implement the Internet Key Exchange (IKE) protocol. This redbook also includes other new features, such as the policy engine, digital certificate and LDAP support, and QoS. The VPN scenarios are enhanced to reflect the latest implementation of IPSec and L2-tunneling functionality.

In this redbook we delve further into these scenarios by showing you how to implement solutions that exploit Data Link Switching (DLSw), IP Bridging Tunnels, Enterprise Extender (HPR over IP), APPN DLUR, TN3270, and Tunneling on layer 2 (L2TP, L2F, PPTP) through an IPSec tunnel.

A working knowledge of the IPSec protocols is assumed.
