"Enterprise Application Integration" provides an interesting introduction to the important topic of EAI (Enterprise Application Integration). EAI plays a key role in many businesses across many scenarios (for example, implementing an Enterprise Application and/or integrating the technologies of an acquired company), so this book covers an important topic. This book as a whole is oriented towards technologically-savvy individuals, but several sections of the book, such as the coverage of "what is EAI" should appeal to, and be of great value to, a wide audience. Organizations that are able to integrate their applications and data sources have a distinct competitive strategic utilization of company data and technology for greater efficiency and profit. But IT managers attempting integration face daunting challenges--disparate legacy systems; a hodgepodge of hardware, operating systems, and networking technology; proprietary packaged applications; and more. Enterprise Application Integration (EAI) offers a solution to this increasingly urgent business need. It encompasses technologies that enable business processes and data to speak to one another across applications, integrating many individual systems into a seamless whole. Enterprise Application Integration provides a comprehensive examination of EAI. You will find an overview of EAI goals and approaches, a review of the technologies that support it, and a roadmap to implementing an EAI solution. You will also find an in-depth explanation of the four major types of data-level, application interface-level, method-level, and user interface-level. The book describes in detail the middleware models and technologies that support these different approaches, * Application servers, including the use of Enterprise JavaBeans (EJB) and ActiveX * Message-oriented middleware (MOM) and remote procedure calls (RPCs) * Distributed objects, looking at CORBA and COM * Database-oriented middleware and standards, including ODBC, JDBC, and OLE DB * Java middleware standards * Message brokers * New process automation and workflow technology This practical guide to implementing an EAI solution leads you through all the major steps, including identifying sources of data, building the enterprise metadata model, process integration, identifying application interfaces, mapping information movement, selecting and applying the technologies, testing, and maintenance. Other key topics include integrating packaged applications such as SAP R/3 and PeopleSoft, integrating the supply chain using EAI, the role of XML, and process automation. Comprehensive, practical, and clearly written, this essential resource will help anyone involved in this important business area understand the nature of EAI, its tools and techniques, and how to apply it for a significant business advantage.

This book is a must-read for anyone interested in bringing the power of Enterprise Application Integration (EAI) to their enterprise. As corporate dependence on technology has grown more complex and far-reaching, the great promise of EAI has emerged as an important solution for IT management. EAI meets the new need for a method of integrating disparate applications into a unified set of business processes. Renowned EAI expert David Linthicum demystifies the key concepts, teaches the critical techniques, and outlines relevant enabling technologies, allowing IT professionals to unlock the massive potential of EAI.

With this book as your guide, you will gain:

• 
  
• The skills to achieve the greatest ROI on an IT investment
  
• The knowledge necessary to categorize and evaluate a wide variety of integration technologies
  
• Techniques and tools required to EAI-enable your enterprise including state-of-the-art message brokers and application servers
