You will also find an in-depth explanation of the four major types of EAI: When using the point-to-point approach, integrating applications comes down to altering each application to be able to send and receive messages. Middleware hides the complexities of the underlying operating system and network in order to facilitate the easy integration of various systems in the enterprise.
This was clear from the earliest days of EAI when most, if not all, integration efforts focused on bundling packaged applications among themselves as well as among the other applications in the enterprise.

Indeed, that “ancient” technology has probably remained critical to the workings of your enterprise. Anoop added it Feb 20, Moreover, the need to integrate those systems with packaged systems has been intensified by the popularity of packaged applications such as SAP, PeopleSoft, and Baan.

In doing so, however, you generally have to alter the source system where the information is coming from with the target system where the information is going to in order to make use of the middleware.

As we have previously suggested, application integration has been going on for years, using a broad range of connection technology. These applications came about when traditional mainframe systems failed to solve departmental problems or, more likely, did not solve them quickly enough.
Queensland University of Technology. For example, when integrating a custom accounting system running on Windows with a custom inventory control aplpication running on the mainframe, you may select a message-queuing enterprie product to allow both systems to share information.
