Key Features Architecture, syntax, development and composition of Business Processes and Services using BPEL Advanced BPEL features such as compensation, concurrency, links, scopes, events, dynamic partner links, and correlations Oracle BPEL Process Manager and BPEL Designer Microsoft BizTalk Server as a BPEL server Book Description Web services provide the basic technical platform required for application interoperability. They do not, however, provide higher level control, such as which web services need to be invoked, which operations should be called and in what sequence. Nor do they provide ways to describe the semantics of interfaces, the workflows, or e-business processes. BPEL is the missing link to assemble and integrate web services into a real business process BPEL4WS standardizes process automation between web services. This applies both within the enterprise, where BPEL4WS is used to integrate previously isolated systems, and between enterprises, where BPEL4WS enables easier and more effective integration with business partners. In providing a standard descriptive structure BPEL4WS enables enterprises to define their business processes during the design phase. Wider business benefits can flow from this through business process optimization, reengineering, and the selection of most appropriate processes . Supported by major vendors - including BEA, Hewlett-Packard, IBM, Microsoft, Novell, Oracle, SAP, Sun, and others - BPEL4WS is becoming the accepted standard for business process management. This book provides detailed coverage of BPEL4WS, its syntax, and where, and how, it is used. It begins with an overview of web services, showing both the foundation of, and need for, BPEL. The web services orchestration stack is explained, including standards such as WS-Security, WS-Coordination, WS-Transaction, WS-Addressing, and others. The BPEL language itself is explained in detail, with Code snippets and complete examples illustrating both its syntax and typical construction. Having covered BPEL itself, the book then goes on to show BPEL is used in context. by providing an overview of major BPEL4WS servers. It covers the Oracle BPEL Process Manager and Microsoft BizTalk Server 2004 in detail, and shows how to write BPEL4WS solutions using these servers. What you will learn Chapter 1 provides a detailed introduction to BPEL and Service Oriented Architecture (SOA). It discusses business processes and their automation, explains the role of BPEL, web services, and Enterprise Service Buses (ESB) in SOA, provides insight into business process composition with BPEL, explains the most important features, compares BPEL to other specifications, provides an overview of BPEL servers, and discusses the future of BPEL. Chapter 2 provides a detailed introduction to the Web Services Technology Stack. It discusses the important standards and specifications for using BPEL and implementing SOA with web services, such as WS-Security, WS-Addressing, WS-Coordination, WS-AtomicTransaction, WS-BusinessActivity, WS-Reliable Messaging, etc. Chapter 3 discusses the composition of web services with BPEL. The chapter introduces the core concepts of BPEL and explains how to define synchronous and asynchronous business processes with BPEL. The reader gets familiar with BPEL process structure, partner links, sequential and parallel service invocation, variables, conditions, etc. Chapter 4 goes deeper into the BPEL specification and covers advanced features for modeling complex business processes. Advanced activities, scopes, serialization, fault handing, compensations, event handling, correlation sets, concurrent activities and links, process lifecycle, and dynamic partner links are covered in detail. Chapter 5 explains how to use the Oracle BPEL Process Manager for deploying and executing business processes defined in BPEL. It describes the server architecture, tools, features, and common approaches for managing and debugging BPEL processes. The chapter also looks at graphical development of BPEL processes using Oracle BPEL Designer for JDeveloper and for Eclipse. Chapter 6 takes a detailed look at the advanced features of the Oracle BPEL Process Manager including extension functions, dynamic parallel flows, Web Services Invocation Framework, Java embedding, Notification service, Workflow service, Identity service, and Oracle BPEL Server APIs.

The question, "Why isn't Oracle using my index?" must be one of the most popular (or perhaps unpopular) questions ever asked on the Oracle help forums. You've picked exactly the right columns, you've got them in the ideal order, you've computed statistics, you've checked for null columns—and the optimizer flatly refuses to use your index unless you hint it. What could possibly be going wrong? If you've suffered the frustration of watching the optimizer do something completely bizarre when the best execution plan is totally obvious, or spent hours or days trying to make the optimizer do what you want it to do, then this is the book you need. You'll come to know how the optimizer thinks, understand why it makes mistakes, and recognize the data patterns that make it go awry. With this information at your fingertips, you will save an enormous amount of time on designing and trouble-shooting your SQL. The cost-based optimizer is simply a piece of code that contains a model of how Oracle databases work. By applying this model to the statistics about your data, the optimizer tries to efficiently convert your query into an executable plan. Unfortunately, the model can't be perfect, your statistics can't be perfect, and the resulting execution plan may be far from perfect. In Cost-Based Oracle Fundamentals, the first book in a series of three, Jonathan Lewis—one of the foremost authorities in this field—describes the most commonly used parts of the model, what the optimizer does with your statistics, and why things go wrong. With this information, you'll be in a position to fix entire problem areas, not just single SQL statements, by adjusting the model or creating more truthful statistics.

SQL (Structured Query Language) is a standard programming language for generating, manipulating, and retrieving information from a relational database. If you're working with a relational database--whether you're writing applications, performing administrative tasks, or generating reports--you need to know how to interact with your data. Even if you are using a tool that generates SQL for you, such as a reporting tool, there may still be cases where you need to bypass the automatic generation feature and write your own SQL statements. To help you attain this fundamental SQL knowledge, look to Learning SQL, an introductory guide to SQL, designed primarily for developers just cutting their teeth on the language. Learning SQL moves you quickly through the basics and then on to some of the more commonly used advanced features. Among the topics discussed: The history of the computerized database SQL Data Statements--those used to create, manipulate, and retrieve data stored in your database; example statements include select, update, insert, and delete SQL Schema Statements--those used to create database objects, such as tables, indexes, and constraints How data sets can interact with queries The importance of subqueries Data conversion and manipulation via SQL's built-in functions How conditional logic can be used in Data StatementsBest of all, Learning SQL talks to you in a real-world manner, discussing various platform differences that you're likely to encounter and offering a series of chapter exercises that walk you through the learning process. Whenever possible, the book sticks to the features included in the ANSI SQL standards. This means you'll be able to apply what you learn to any of several different databases; the book covers MySQL, Microsoft SQL Server, and Oracle Database, but the features and syntax should apply just as well (perhaps with some tweaking) to IBM DB2, Sybase Adaptive Server, and PostgreSQL. Put the power and flexibility of SQL to work. With Learning SQL you can master this important skill and know that the SQL statements you write are indeed correct.
