Enterprise Application Integration, or EAI, is a buzzword that gives a name to the informal process that’s been going on for years—the integration of various. Enterprise Application Integration has 25 ratings and 1 review. Steve said: This is a popular introduction to EAI – short on detail, long on asinine (a. Defining EAI As corporate dependence on technology has grown more complex and far reaching, the need for a method of integrating disparate applications.

Brian Mulloy rated it it was ok Nov 22, He has almost twenty years of experience in the integration-technology industry, most recently as CTO of Mercator Software, Inc. Then set up a personal list of libraries from your profile page by clicking on your user name at the top right of any screen. The book describes in detail the middleware models and technologies that support these different approaches, including: Tags What are tags?
Because the architecture is already distributed–riding on open systems with open, better-defined interfaces–it lends itself well to integration when compared to traditional, centralized computing architecture. Developers, generally speaking, deal with an API on each system, and the middleware handles the passing of information through the different systems on behalf of the application.
In the early days of computing, information was processed on centralized platforms. Put briefly, EAI is the unrestricted sharing of data and business processes among any connected applications and data sources in the enterprise.
View table of contents. The only limitations that developers face are the specific features and functions of applicatin application interfaces. EAI and the Modern Enterprise. Bloggat om Enterprise Application Integration. For example, when integrating a custom accounting system running on Windows with a custom inventory control system running on the mainframe, you may select a message-queuing middleware product to allow both systems to share information.
Enterprise Application Integration
Available also in a print edition. While these benefits do exist to a certain degree, distributed systems, though architecturally elegant, are difficult to implement. 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 enteprrise business advantage.
enterpprise Message brokers also assure that messages are delivered in the correct sequence and in the correct context of the application. Enterprise architects will be called upon to make some unpopular decisions. As a result, the enterprise as a whole was left with a “system” that is nearly impossible to integrate without fundamental re-architecture–and a significant investment of precious funds.
There are no discussion topics on this book yet. Defining the Value Step The demand of the enterprise is to share data and processes without having to make sweeping changes to the applications or data structures see Figure 1. The primary limitation is that middleware that uses message queuing or remote procedure calls RPCs only provides point-to-point solutions–that is, linkage between system A and system B.
This is applicatino to the fact that the point-to-point middleware layer only provides a program interface, applicatin thus the programs must change to accommodate the middleware. Features of the traditional system include both database and business processing existing together within the same environment.

This single location in Queensland: 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.
S.lijthicum Application Integration David S. Applying Technology If EAI articulates the problem, then traditional middleware has sought to articulate the solution–sort of.
Separate different tags with a comma. These include call center applications, sales automation applications, and inventory control applications. The Value of Frameworks. The approach and enabling technology you leverage depends on the requirements of the problem domain. Return to Book Page. You will also find an in-depth explanation of the four major types of EAI: There are two basic approaches: This can be accomplished with any number of message-oriented middleware MOM products e.
