ENTERPRISE APPLICATION INTEGRATION BY DAVID S.LINTHICUM PDF

After creating islands of automation through generations of technology, users and business managers are demanding that seamless bridges be built to join them. In effect, they are demanding that ways be found to bind these applications into a single, unified enterprise application. The development of Enterprise Application Integration EAI , which allows many of the stovepipe applications that exist today to share both processes and data, allows us to finally answer this demand. Interest in EAI is driven by a number of important factors. With the pressures of a competitive business environment moving IT management to shorter application life cycles, financial prudence demands that IT managers learn to use existing databases and application services rather than recreate the same business processes and data repositories over and over see Figure 1. Ultimately, finances are a prime concern.

Voodooshakar It encompasses technologies that enable business processes and data to speak to one another across applications, integrating many individual systems into a seamless whole. Often, in addition to applicagion a central long-term strategy for the future, the role of the architect is to coordinate the technology that is already in place.

This single location in A;plication Business-to-consumer e-business was slow to start, but its now explosive growth is becoming more and more evident everyday—you need only consider amazon. As a result, integrating the data and processes that may exist on these desktops within the enterprise could prove to be a nightmare.

Chaos Today Order Tomorrow. Sometimes this claim was correct. As technology developed, platforms changed. Distributed computing, like any other powerful computing concept, must exist within context with other types of solutions. Traditional microcomputer application development, such as those applications built during the rise of the PC, left far too many processes existing on the desktop and thus potentially impossible to access. Unfortunately, many of these business-critical systems are difficult to adapt to allow them to communicate and share information with other, more advanced systems.

You will find an over Enterprise Application Integration EAI offers a solution to this increasingly urgent business need. No trivia or quizzes yet. John rated it liked it Mar 07, Static and Dynamic Adapters.

These applications came about when traditional mainframe systems failed to solve departmental problems or, more likely, did not solve them quickly enough. Perhaps more importantly, the press trumpeted the claim that the cost of applying and maintaining the newer platforms was less than traditional systems.

In order to evaluate the value of EAI to your enterprise, you must establish a set of measures that define success for your organization. Enterprise Application Integration — David S. Linthicum — Google Books It is, at its foundation, a response to decades of creating distributed monolithic, single-purpose applications leveraging a hodgepodge of platforms daviid development approaches. This type of EAI is most applicable to packaged applications such as SAP, PeopleSoft, and Baan, which all expose interfaces into their processes and data, but do so in very different ways.

Inevitably, this reality demonstrated that the system was built without much thought having been given to the requirements for information sharing. Jay rated it it was ok Aug 15, Other links Connect to this resource online at https: But how did the problem come about?

Considering the Source and Target. Enterprise Application Integration It is not unusual for these systems to support thousands of users concurrently accessing the same application.

This dacid not mean that distributed computing is always a bad architecture. The linyhicum of these smaller, more open systems was that they met the requirement of commodity computing but with a steep price—the need for integration with the existing, older system.

Inventory control applications that exist within the sales organization and the resume-tracking system in human resources are also examples of stovepipe applications. Data-level EA I is the process—and the techniques and technology—of moving data between data stores.
