Because EAI is very good at integrating various applications and data stores, it is able to extend its reach outside the enterprise to include both trading partners and customers within the enterprise integration architecture.

First, the enterprise needs to understand the large-picture architecture.

Enterprise Application Integration by David S. Linthicum

Undoubtedly, a number of stovepipe systems are in your enterprise–for example, inventory control, sales automation, general ledger, and human resource systems. Developers leverage these interfaces to access both business processes and simple information. While mainframes continue to make up the majority of traditional systems, minicomputers and even large UNIX systems may also correctly be called traditional systems.

View table of contents. Microcomputer Systems Microcomputer systems–personal computers–that exist within the enterprise untegration represent a significant challenge to those who seek to implement EAI within the corporation.

For example, the author states several times infegration SAP needs a richer collection of APIs in order to connect to other application. Organizations that are able to integrate their applications and data sources have a distinct competitive advantage: The primary limitation is that middleware that uses message queuing w.linthicum remote procedure calls RPCs only provides point-to-point solutions–that is, linkage between system A and system B.

This can be described as extracting information from one database, perhaps processing that information as needed, and updating it in another database.

EAI is able to take many diverse systems and bundle them in such a way that they appear–and function–as a monolithic and unified application see Figure 1. Author Linthicum, David S. It is not unusual for these systems to support thousands of users concurrently accessing the same application.

This person or office is responsible for overseeing a centralized architecture and making sure that technology and solutions selected for the enterprise are functionally able to interact well with one another.

To address the problem of architectural foresight, many organizations have created the role of the enterprise architect. When using the point-to-point approach, integrating applications comes down to altering each application to be able to send and receive messages.

More importantly, we approach this old problem with a new set of technologies designed specifically for 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. 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.

In the world of distributed computing, middleware usually is a means for connecting clients to servers, clients to clients, and servers to servers without having to navigate through many operating systems, networks, or resource server layers.

Applying Technology If EAI articulates the problem, then traditional middleware has sought to articulate the solution–sort of.

Distributed computing implies that distribution provides clear benefits, including scalability and fault-tolerance. These applications came about when traditional mainframe systems failed to solve departmental problems or, more likely, did not solve them quickly enough.

This enables any application or data store to share information with any other application or data store that exists within the supply chain scenario. There are no discussion topics on this book yet. For example, point-to-point middleware, while providing value within the enterprise, does not–and cannot–provide the ultimate solution. For example, the new SAP system implemented in accounting is a natural stovepipe application at the module level.

The book aim either at high-level managers to give them an introduction of what EAI is or at students who don’t know anything about EAI. While the business case for EAI is clear to most people versed in the technical aspects of this discussion, it might not be as clear to those who really need to understand its value.

They are very useful, but my experience at the time of this review is all but the wealthiest customers are being slow to deeply adopt due to technical skills transfer in their staffs, etc. I’d like to read this book on Kindle Don’t have a Kindle?

Ben added it Aug 31, Information technology decisions tended to be made at the department level, with each department selecting technology and solutions around its own needs and belief structures. EAI has been brought into play as a mechanism, not only to integrate existing enterprise applications, but also to integrate and free the information from the new generation of packaged applications. It must be measured enterprise by enterprise.

There are two basic approaches: Alexa Actionable Analytics for the Web. Worse still, traditional middleware demands significant alterations to the source and target systems, embedding the middleware layer into the application or data store.

One person found this helpful. In the rush to incorporate these new systems, most enterprises applied minimal architectural foresight to the selection of platforms and applications. It encompasses technologies that enable business processes and data to speak to one another across applications, integrating many individual systems into a seamless whole. IT managers made many of their decisions based on their perception of the current technology market. Second, new technology must be leveraged to solve the EAI problem.
