system architecture, SAP ERP and CRM implementation, Oracle ERP E-Business
|
SAP as the ERP and CRM that require a separate database, but the accompanying data is not synchronized the problem gave birth to SAP MDM (Master Data Management System). Defects because the system architecture, SAP had to do more and more large and complex systems. I have experienced SAP ERP and CRM implementation and application of the last two systems I have found the same definition of data structures are not uniform, often derived from a system, in the external system (non-SAP), after finishing batch input to another system , and the same business data structures in the two systems are not the same! All successful SAP applications, there are a large number of plug-ins for its services, systems (non-SAP) exist, SAP has introduced a number of similar products, which is really a last resort, and extremely inefficient way to whom. In addition the majority of SAP customers rely on integrated applications BAPI, RFC-specific interface standards such as SAP, which makes its interaction with the outside world in the development and maintenance costs. Other hand, Oracle, and open J2EE architecture, so that maintenance, development, and outsourcing or managed costs are relatively much lower, so that enterprises can put the main energy and financial aspects of business process reengineering and optimization.
Oracle ERP E-Business Suite is a complete Internet-based solutions that enable the deployment, use, maintenance costs low, while ease of use is excellent. SAP is still relying on a dedicated SAP GUI or the BSP or the Portal, its complexity and compatibility problems so that implementation of the consultant is not only a headache, has also been criticized by users.
