This guide is essential for anyone involved in developing applications, evaluating products, designing systems, or engineering products related to transaction processing. It offers a clear understanding of how transaction processing systems operate and how to effectively utilize them. Key topics include the architecture of transaction processing monitors, transactional communication paradigms, and recovery mechanisms for transaction and system failures. With the rapid increase in the use of transaction processing systems across business, industry, and government—especially due to the rise of electronic commerce—many developers are encountering these applications for the first time and require practical techniques. Software engineers involved with operating systems, communications systems, and programming tools relevant to transaction processing will find valuable insights in this comprehensive presentation. Rich with real-world examples, it covers commercial transaction processing systems, the transactional aspects of database servers, messaging systems, Internet servers, and object-oriented systems, along with their subsystems. The book features easy-to-read descriptions of fundamentals, practical issues faced by developers, and explanations of major products and standards, including those from IBM, X/Open, BEA Systems, Digital, Transarc, AT&T/NCR, Tandem, OMG, and Microsoft.

This book introduces the main ideas and concepts behind core and extended Web services technologies and provides students with a primer for each of the major technologies that have emerged in this space. In addition, Understanding Web Services summarizes the major architectural approaches to Web services, examines the role of Web services within the .NET and J2EE communities, and provides information about major product offerings from Microsoft, IBM, IONA, HP, Sun, BEA, Oracle, and others. Key topics XML facilities for structuring and serializing data, how WSDL maps services onto communication protocols and transports, WSDL support for RPC-oriented and document-oriented interactions and UDDI data formats.
