This can be accomplished with any number of message-oriented middleware MOM products e. While it may be possible to develop a “common sense” set of metrics to evaluate the success of EAI, the reality is that in most cases they must be significantly adjusted on a case-by-case basis to account for the many factors that exist in davud given enterprise. Perhaps more importantly, the press trumpeted the claim that the cost of applying and maintaining the newer platforms was less than traditional systems.

Enterprise Application Integration

Remember, EAI at its heart is the ability to leverage any existing system by finding a reliable point-of-integration. Mainframes, UNIX servers, NT servers, and even proprietary platforms whose names have been forgotten, constitute the technological base for most enterprises.

Many organizations seek new methodologies to assist them in this process and look closely at the best practices.

Liinthicum About Enterprise Applic Packaged applications are natural stovepipes. 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.

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. And, perhaps most importantly, what are the methods that best measure success? Public Private login e. The University of Sydney. The book describes in detail the middleware models and technologies that support these different approaches, including:.

With Safari, you learn the way you learn best. Refresh and try again. Interest in EAI is driven by a number of important factors. It may also include the transformation and application of business logic to the data that is being extracted and loaded.

Evolution of Stovepipes Within enterprises enferprise many stovepipe applications that address and solve very narrow problems within departments.

This can be described as extracting information from one database, perhaps processing that information as needed, and updating it in another database. Saeid is currently reading it Jun 30, Adel Haider is currently reading it Jul 17, Undoubtedly, a number of stovepipe systems are in your enterprise–for example, inventory control, sales automation, general ledger, and human resource systems. Brian Mulloy rated it it was ok Nov 22, Leveraging Frameworks for EAI. This allows any and all information required for all transactions to be immediately available no matter where the information is located in the enterprise.

For generations, systems have been built that have served a single purpose for a single set of users without sufficient lknthicum to integrating these systems into larger systems and multiple applications.

Chris Reesman marked it as to-read May 15, The book describes in detail the middleware models and technologies that integratioj these different approaches, including: 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.

Traditional Systems Traditional systems also known as “legacy systems” are stovepipe applications that may exist with many other stovepipe applications in a centralized environment.

In short, middleware is the underlying technology of EAI. External resources may include a database server, a queue, a terminal, Enterprise Resource Planning ERP applications, custom API, or access to real-time information. Even so, without a significant gain in user productivity or a reduction in error rate, the integration effort between two systems has minimal value.

While there always exists the option of replacing these older systems, the cost of doing so is generally prohibitive. If a enterpeise leverages a single, host-based computer system with few applications existing on that platform, only a few thousand users would have only limited benefit from EAI.

EAI is no exception. Anoop added it Feb 20, The integration of applications to save precious development dollars creates a competitive edge for corporations who share application information either within the corporation or with trading partners.

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. These applications came about when traditional mainframe systems failed to solve departmental problems or, more likely, did not solve them quickly enough.

Traditional microcomputer application development, such as dvaid applications built during the rise of the PC, left far too many processes existing on the desktop and thus potentially impossible to access.
