PL/SQL, Oracle's programming language for stored procedures, delivers a world of possibilities for your database programs. PL/SQL supplements the standard relational database language, SQL, with a wide range of procedural features, including loops, IF-THEN statements, advanced data structures, and rich transactional control--all closely integrated with the Oracle database server. Knowing where to start with Oracle's procedural language is not always obvious to a newcomer, especially considering the language's feature set and the sheer size of the official documentation (not to mention Oracle's ever-increasing number of pre-built PL/SQL programs). But Learning Oracle PL/SQL offers the signposts and guidance you need to come up to speed on the language, delivered in a manageable number of pages while covering all the essentials. Topics include: PL/SQL--what is it, and why use it? Why use PL/SQL instead of Java? Syntax and examples of all core language constructs Creating, using, and reusing stored procedures, functions, and packages Building web-based applications using PL/SQL features available "out of the box" (such as PL/SQL Server Pages) Securing PL/SQL programs against attack Benefits of third-party developer tools and integrated development environments Connecting PL/SQL to email, Java, and the Internet Meticulously crafted with all-new examples downloadable from examples.oreilly.com/learnoracle, the book addresses language features available in all versions of Oracle, from Oracle7 to Oracle8i to Oracle9i. Learning Oracle PL/SQL was written by PL/SQL experts Bill Pribyl and Steven Feuerstein, whose easy-to-read style and attention to detail has made other O'Reilly books (such as the bestselling Oracle PL/SQL Programming) very popular among Oracle developers worldwide. Learning Oracle PL/SQL is meant for a wide range of target audiences, including both beginning programmers and those already experienced with other programming languages. Whether you are a new developer, a crossover programmer from another database system, or a new database administrator who needs to learn PL/SQL, this book will get you well on your way. It is the perfect introduction to Oracle PL/SQL Programming, also by Pribyl and Feuerstein.

A rigorous and practical framework for modeling business systems Pares object modeling down to its core concepts, making it easier than ever. Twelve object collaboration patterns that address virtually any business scenario Powerful techniques–not fancy notation! Streamlined Object Modeling presents the first rigorous, practical framework for object modeling complex business domains, rules, and systems. Three world-renowned leaders in object development have pared object modeling down to the core concepts for all business domains, business rules, and business services. Starting from the first principles of "object think," the authors offer a fully integrated approach to building, validating, and critiquing object models. Coverage includes: Proven principles and techniques for successfully modeling the structure and operations of any business domain. Guidelines for finding and associating objects, assembling object models, and distributing system behavior among objects. Rigorous methods for discovering, organizing, and implementing business rules around objects. Twelve all-encompassing "collaboration patterns"–what they represent, how they relate, and how to apply them. Five kinds of business rules, three types of services, and six categories of properties completely specify object-oriented business requirements From start to finish, the book makes extensive use of examples drawn from real commercial applications. To illustrate how streamlined object modeling flows from analysis to code, it also presents a complete case study derived from a real-world application, and implemented in two leading object-oriented languages-Java, and the Squeak implementation of Smalltalk.

While the XML "buzz" still dominates talk among Internet developers, the critical need is for information that cuts through the hype and lets Java programmers put XML to work. Java & XML shows how to use the APIs, tools, and tricks of XML to build real-world applications, with the end result that both the data and the code are portable. This second edition of Java & XML adds chapters on Advanced SAX and Advanced DOM, new chapters on SOAP and data binding, and new examples throughout. A concise chapter on XML basics introduces concepts, and the rest of the book focuses on using XML from your Java applications. Java developers who need to work with XML, or think that they will in the future--as well as developers involved in the new peer-to-peer movement, messaging, or web services--will find the new Java & XML a constant companion. This book covers: The basics of XML, including DTDs, namespaces, XML Schema, XPath, and XSL The SAX API, including all handlers, the SAX 2 extensions, filters, and writers The DOM API, including DOM Level 2, Level 3, and the Traversal, Range, CSS, Events, and HTML modules. The JDOM API, including the core, a look at XPath support, and JDOM as a JSR Using web publishing frameworks like Apache Cocoon Developing applications with XML-RPC Using SOAP and UDDI for web services Data Binding, using both DTDs and XML Schema for constraints Building business-to-business applications with XML Building information channels with RSS and dynamic content with XSP Includes a quick reference on SAX 2.0, DOM Level 2, and JDOM.

Inside XSLT is designed to be a companion guide to Inside XML. This example oriented book covers XML to HTML, XML to Music, XML with Java, style sheet creation and usage, nodes and attributes, sorting data, creating Xpath expressions, using Xpath and XSLT functions, namespaces, names templates, name variables, designing style sheets and using XSLT processor API's, the 56 XSL formatting objects, the XSLT DTD, and much much more.

Have you ever needed to share processing between two or more computers running programs written in different languages on different operating systems? Or have you ever wanted to publish information on the Web so that programs other than browsers could work with it? XML-RPC, a system for remote procedure calls built on XML and the ubiquitous HTTP protocol, is the solution you've been looking for. Programming Web Services with XML-RPC introduces the simple but powerful capabilities of XML-RPC, which lets you connect programs running on different computers with a minimum of fuss, by wrapping procedure calls in XML and establishing simple pathways for calling functions. With XML-RPC, Java programs can talk to Perl scripts, which can talk to Python programs, ASP applications, and so on. You can provide access to procedure calls without having to worry about the system on the other end, so it's easy to create services that are available on the Web.XML-RPC isn't the only solution for web services; the Simple Object Access Protocol (SOAP) is another much-hyped protocol for implementing web services. While XML-RPC provides fewer capabilities than SOAP, it also has far fewer interoperability problems and its capabilities and limitations are much better understood. XML-RPC is also stable, with over 30 implementations on a wide variety of platforms, so you can start doing real work with it immediately. Programming Web Services with XML-RPC covers the details of five XML-RPC implementations, so you can get started developing distributed applications in Java, Perl, Python, ASP, or PHP. The chapters on these implementations contain code examples that you can use as the basis for your own work. This book also provides in-depth coverage of the XML-RPC specification, which is helpful for low-level debugging of XML-RPC clients and servers. And if you want to build your own XML-RPC implementation for another environment, the detailed explanations in this book will serve as a foundation for that work.

XML has been the biggest buzzword on the Internet community for the past year. But how do you cut through all the hype and actually put it to work? Java revolutionized the programming world by providing a platform-independent programming language. XML takes the revolution a step further with a platform-independent language for interchanging data. Java and XML share many features that are ideal for building web-based enterprise applications, such as platform-independence, extensibility, reusability, and global language (Unicode) support, and both are based on industry standards. Together Java and XML allow enterprises to simplify and lower costs of information sharing and data exchange. Java and XML shows how to put the two together, building real-world applications in which both the code and the data are truly portable. This book covers: The basics of XML Using standard Java APIs to parse XML Designing new document types using DTDs and Schemas Writing programs that generate XML data Transforming XML into different forms using XSL transformations (XSL/T) XML-RPC Using a web publishing framework like Apache-Cocoon This is the first book to cover the most recent versions of the DOM specification (DOM 2), the SAX API (SAX 2) and Sun's Java API for XML.

This compact guide provides the jump-start Oracle developers need to make the transition from traditional programming to the development of useful Web applications for Oracle8i. Even readers who start out knowing nothing about HTML, PL/SQL, or Oracle's other tools will learn how to create simple Web applications in a matter of days. The book focuses on Oracle8i, but also covers Web development for earlier Oracle versions (Oracle8 and Oracle7). Background: The explosion in the use of the Internet and the Web has resulted in a whole new way of doing business. Developers who only yesterday were using COBOL to write accounts payable systems are now being asked to create a broad range of new Internet-based applications ranging from electronic commerce (e-commerce) Web sites to internal data warehouses to enterprise resource planning (ERP) systems. Unfortunately, the filesystem architectures of most Web systems aren't up to the task. The new breed of Web applications -- which are quickly becoming critical resources that companies need to survive -- demand a platform that provides production-quality tools for content management, application development, and application integration. And current Web techniques are inadequate in many ways. Oracle8i, Oracle's "Internet database," gives Web developers a way to build Web technology on top of a relational database, rather than on a traditional filesystem. With Oracle8i, companies can apply well understood, reliable, production-quality database methodologies to Web content management. Oracle8i also supports a wide variety of application development platforms and tools that are tightly integrated to the core database. Finally, Oracle8i supports technologies that help companies tie their Web-based applications into legacy applications. There is a lot to learn in Oracle8i. Not only does it enhance basic database features, it introduces Java and a variety of Web development tools. Oracle8i provides a soup-to-nuts platform for Web site and Web application development that extends traditional database concepts to Web content. It replaces the traditional filesystem used by most Web servers with a database management system. Many users are intimidated by the vast array of new technologies in Oracle8i. And yet, they are under pressure to use these technologies to build complex Web applications right now. This book gives such users a way to start using Oracle8i immediately to create useful Web applications. It is a concise, easy-to-read guide to the basic technologies developers need to understand in order to build Web applications. Contains: The book describes the following Web development tools: PL/SQL-- a structured programming language that combines procedural constructs and standard SQL. It offers such features as cursors, loops, conditional and sequential control statements, exception handlers, records, tables, and constructs for developing modular code (functions, procedures, and packages). PL/SQL Toolkit -- a set of PL/SQL packages supplied by Oracle for use in developing Web applications. HTML -- an ASCII-based markup language used to create Web pages. WebDB -- A software system for building, monitoring, and creating content-driven Web sites; it allows users to use a Web browser to access and store information in the Oracle8i database. Oracle Application Server (OAS) -- an extensible Web server that uses plug-in programs called cartridges to allow database-integrated Web systems to be developed in a variety of languages (e.g., PL/SQL, Java, Perl). XML -- An emerging standard for creating self-describing documents. It is similar to HTML but allows you to create your own markup tags. XML is expected to be a key technology in electronic commerce systems. The book also presents several fully realized sample Web applications that will teach you how to build such applications of your own. NOTE: Although this book touches on the Java features of Oracle8i, it doesn't cover Java development per se. Switching to Java represents an enormous change for most Oracle developers. This book provides an evolutionary path for readers who want to do useful Oracle8i Web development now, using mostly familiar tools. Additional books will provide Java training for those who have mastered these Web tools and want to take the next step.

MySQL and mSQL are popular and robust database products that support key subsets of SQL on both Linux and Unix systems. Both products are free for nonprofit use and cost a small amount for commercial use. Even a small organization or web site has uses for a database. Perhaps you keep track of all your customers and find that your information is outgrowing the crude, flat-file format you started with. Or you want to ask your web site's visitors for their interests and preferences and put up a fresh web page that tallies the results. Unlike commercial databases, MySQL and mSQL are affordable and easy to use. If you know basic C, Java, Perl, or Python, you can quickly write a program to interact with your database. In addition, you can embed queries and updates right in an HTML file so that a web page becomes its own interface to the database. This book is all you need to make use of MySQL or mSQL. It takes you through the whole process from installation and configuration to programming interfaces and basic administration. Includes reference chapters and ample tutorial material. Topics include: Introductions to simple database design and SQL Building, installation, and configuration Basic programming APIs for C, C++, Java (JDBC), Perl, and Python CGI programming with databases in C and Perl Web interfaces: PHP, W3-mSQL, Lite, and mSQLPerl
