This prevented the SAP to provide real-time analysis, for example, "Daily Business Intelligence." When information is transferred from one system to another system, a process, information has become obsolete.
SAP data model is basically divided based on different technologies, which can not be real-time analysis and data needs to be copied from one system to another system, easily lead to distortion of information. In the SAP system, the integration between modules are integrated in the program level, rather than in the data integration layer.
Oracle stores all of the information in a single comprehensive data model inside. This ensures that all application modules inside information is consistent, to avoid redundancy of information or failure. SAP through the acquisition of trying to build a complete application suite, which has a number of data model. The results split the data source allows businesses to share information that is almost impossible to obtain because there is no one single "source of truth."
In terms of successful implementation in a system inside the case, or so the benefits to the customer perspective, ORACLE attest to the importance of a comprehensive integrated system. Of all the ERP product suppliers, ORACLE This architecture is unique.
In the system integration on the
Even in its own system modules, SAP is also integrated in the application level, rather than the data level integration. This means that a lot of information there are several versions of an object, stored in different systems inside (eg HR work center and logistics center is inside the duplication of work). They do not provide a version of the "truth", which will lead to data inconsistencies problems.
As and external system integration, SAP and web methods by the composition of partnerships to support the XML (in the Business Connector), rather than to rewrite programs to meet the Internet access and integration. However, this is not a good way. As Gartner has said: "Business Connector to support XML documents and SAP software integration; however, we can see that the cornerstone of SAP is still based on more than 2000 BAPI and ALE technology, Business Connector and then put them on top of the contents of XML converted to BAPI. SAP said this could work, but the overall performance of the BAPI to be slower than pure. "SAP's recently announced WEB services immature, and need more time to become reliable.
In practice, SAP users will still rely mainly on BAPI. Although the 100 partners to use them, but the key question is whether the partners are willing. First of all, SAP's BAPI incomplete and difficult to expand, a number of important business object does not include recently. And many BAPI limited functionality (for example, did not create a new employee BAPI). Based on these functional limitations, many customers were forced to copy the BAPI and then modify them to meet company needs.
There are, BAPI is ABAP written, ABAP is SAP's unique technology. SAP to provide "Connectors" allow the application of technology through a number of the designated call BAPI, such as Microsoft COM or JAVA. However, if some third-party products or legacy systems to support not based on BAPI technology, the user must slow and awkward to use batch import to solve integration issues.
Oracle E-Business Suite for all sub-systems integrated within the module no problem. Unlike SAP, all of ORACLE systems are developed on the same architecture, using the same database.
