i am new "SAP" technology ,Please tell me the Deffination FrameWork , And Reason why we adopt SAP . What is the Advantage of using this ,as we also use (J2EE Architecture) For enterprise level. please If send me net Resource And "URL" Regarding the BAsic Concept of "SAP".
without knowing much about it. I once did participate in a project where we connected a SAP system as back-end to a LotusDomino app as frontend. SAP is german and the leading Enterprise Ressource Planning system of this planet. It is not written in Java, but in C++. They have modules for all parts of business of a company. Controlling departments love it. Marketing departments hate it. You get a overview about the profit, the costs, etc. In J2EE it is used as a backend system, like a relational database. You can use Webservices or JCA to connect to it. With JCA for me it seems to be about calling the SAP BAPIs (transactional function in SAP-system, like stored procedure in RDBMS). The business logic is inside the BAPIs (written by SAP expert). They have their own Internet/Java product/tools line which is called mySap.com. They want to support Java and .net and consider Java more stable. [ November 15, 2002: Message edited by: Axel Janssen ]
