The development of Enterprise Application Integration EAIwhich allows many of the stovepipe applications that exist today to share both processes and data, allows us to finally answer this demand. So, if EAI is the solution, what exactly is it? Although not preferred, it may be the only solution you have in many instances.
The book describes in detail the middleware models and technologies that support these different approaches, including: While this sounds direct and straightforward, in a typical EAI-enabled enterprise, it might mean drawing from as many as one hundred databases and several thousands of tables.
The end state looks more like an ill-planned highway system that was built by many small integration projects but with little strategic value. EAI represents the solution to a problem that has existed since applications first moved from central processors. As we have seen, any stovepipe application is difficult to integrate with the rest of the enterprise.
Acknowledgments About the Author 1. Why a New Direction? It is, at its foundation, a response to decades of creating distributed monolithic, single-purpose applications leveraging a hodgepodge of platforms and development approaches.

The book describes in detail the middleware models and technologies that support these different approaches, including:. 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.
Therefore, in order to accurately assess EAI, you need to weigh both user productivity and error reduction, giving a measure to both. Inevitably, this reality demonstrated that the system was built without much thought having been given to the requirements for information sharing.
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. Then set up a personal list of libraries applictaion your profile page by clicking on your user name at the top right of any screen.
For example, if you want integratipn expand your sales order entry system to allow unknown customers to link to your company Web site and purchase your products, you would have to expose intfgration information using techniques and technology created by EAI. EAI provides a set of integration-level application semantics.
Binding the Home System to a Strangers. In doing so, however, you generally have to alter libthicum source system where the information is coming from with the target system applicatjon the information is going to in order to make use of the middleware.
Selected pages Title Page. Features of the traditional system include both database and business processing existing together within the same environment. Paritosh Chandorkar marked it as to-read Oct 29, This is due to the fact that the point-to-point middleware layer only provides a program interface, and thus the programs must change to accommodate the middleware.
Put briefly, EAI is the unrestricted sharing of data integragion business processes among any connected applications and data sources in the enterprise. You also may like to try some of these bookshopswhich may or may not sell this item.

integrafion The benefit to business is plain: Understanding the Enterprise and Problem Domain. Categories of Java Middleware Standards. Given these significant limitations, it follows that EAI represents a very different method of application integration than that using traditional middleware see Figure 1.
Traditional middleware technology, such as message-queuing software, ties applications together, but these “point-to-point” solutions create single links between many applications as we mentioned previously.
Complicating the situation is the fact that no two microcomputers are exactly alike. The advantage of data-level EAI is the cost of using this approach.
The end result could have been a mixing and matching of technologies and paradigms. For example, accounting may have built their information systems around a mainframe, while human resources leveraged the power of distributed objects, and research and development might have used distributed transaction processing technology. Eugene added it Apr 22, Eitel MaurRobert Winter No preview available – Distributed Systems Simply stated, distributed systems are any number of workstation servers and hosts tied together by a network that supports any number of applications.

Micheal Shallop rated it it was ok Nov 08, As in supply chain integration, business-to-consumer EAI is the process of exposing information within your enterprise to people or entities, known and unknown, that exist outside your dvaid.
Middleware provides developers with an easy way to integrate external resources using a common set of application services.
Enterprise Application Integration
Chaos Today Order Tomorrow. Middleware provided developers and application architects with the ability to bridge many linthiucm systems, bringing them together to form virtual systems. It does, however, urge caution and a broad perspective.
