Enterprise development environment

Tools <------------ Adapters and drivers -----à Servers These adapters have 1) Non-relational data sources ---------- Adabas 2) Relational data sources Integration of Component based applications J2ee connector architecture (JCA) Defines Standard Architecture Adapter Behavior Create once use anywhere Deals with details of underlying application ,databases Liberate application services and information out of the underlying databases . Integration Servers http://www.devchannel.org/devtoolschannel/03/09/11/1444239.shtml



The approaches that each integration server vendor takes are very different ……….and thus solves very different type s of problems .
As such we need to understand approaches in order to select the proper technology for ur problem domain .

Integration servers defined

Integration servers account for differences in application semantics and database schemas …………………..and process information by transforming the structure or format of the information …………


Information routing between applications can b made by using any number of interfaces mechanism ………..
Another good point about these integration servers is that based on the existing functionality of the entity they connect ,they can host functions




Services of Integration servers

;;;;;;

Non – intrusive point of integration -------------XML integration servers (can consume or produce information formatted in a variety of ways )

Integration servers mirrors the way business works ………..

An effective application integration is consist of many components …………..that r routing , reformatting and flow components

Based on asynchronous ,store and forward messaging .

An integration server is a software system that is based on the asynchronous ,store and forward messaging .
