Oracle on SAP advantage of brief, information product based software, R2/R3 system compatibility
|
I contacted SAP Product line is about ten years, engaged in the development of SAP, implementation, application and consulting, among other things, to SAP's ERP and CRM little bit. Oracle product line, contact time later, mainly related to CRM (Oracle, and Siebel) and ERP products. Should be said that the competition in the global high-end ERP, mainly SAP and Oracle competition. SAP as it is more heavy publicity, we know more, so this time highlight the advantages of Oracle for SAP, analysis or in ERP-based products.
As we all know, Oracle is able to provide a large database, middleware and information products and platforms, a comprehensive software company, SAP is based on information product based software company. Oracle has the industry's best database solution, which is ERP system stable and highly efficient operation and provided a fundamental guarantee, SAP mainly through third-party database program, you must run through the SAP-specific interfaces, so that the system hampered efficiency. From a technical architecture perspective, SAP since the early R2/R3 system compatibility problems, with the help of IBM has done a lot to beat the system patch work, system-level software architecture than Oracle and more complex data structures. Instead, Oracle has its own database products, and more forward-looking manner to the system (development) platform and database platform positioned on J2EE above, this software is available for the scalability, ease of maintenance has laid a good foundation. In addition, to achieve the same functionality and speed, SAP needs more than Oracle's hardware support, which is already common knowledge in the industry.
ERP products are required to configure and secondary development, system development platform for the future whether or not advanced maintenance, application extensions, etc. have great impact on work efficiency. SAP Developer ABAP language development in the main, this is SAP founder of the early work in the transplanted IBM mainframe systems. ABAP does not support cross-platform, so SAP to achieve the different hardware and software platform support, but also added to explain the implementation of the different layers and layers. At the same time, ABAP development efficiency is not high, is not conducive to team development, code maintenance and version management red tape and other problems caused by secondary development of the SAP inconvenient. On the contrary, Oracle ERP using J2EE, its open development environment and tools to make choices without restrictions, so that SAP headache problem Oracle here are no longer a problem. Although SAP is also trying to learn Oracle's Fusion technology, introduced Net weaver, but the J2EE development and application do not form a climate, ABAP is still plagued with the nightmare of SAP developers.
Because no one is a better understanding than the Oracle database, so the above ERP information system architecture, SAP would lose at the starting line. The figure is the Oracle and SAP's ERP information system framework for comparison. Oracle in all corporate information is stored in a single database to simplify the information architecture based on the realization of all business processes fully automated, thereby increasing system efficiency. This single data model can reduce deployment costs, IT maintenance costs, internal cross-functional areas to achieve a fully integrated, and enterprise-wide real-time analysis. In contrast, SAP's approach Zeyi a bunch of complex technical and decentralized data model features. Its multiple databases and multiple data model allows the dependence of enterprise-wide analysis becomes difficult and expensive. SAP such an efficient architecture, from early hardware to run fast enough, such a decentralized architecture can improve system speed. However, today's rapid advances in hardware technology, coupled with clustering technology, and minicomputer into the enterprise, SAP is no doubt apparent drawbacks of this architecture. Oracle E-Business Suite provides real-time monitoring of performance indicators in the SAP ERP is not through the secondary development (and perhaps also need to plug third-party program interface) can not be achieved.
