In the ERP system and database, the middle translation layer, allowing data layer separation and processing layer development methodology, not only in applications such as ERP systems integration play a role, but also for the ERP system design is also of great significance. This approach allows the design of ERP software, has nothing to do with the database for the design personnel, in the development of different databases, without attention to the differences between databases, but by EDI translation layer to eliminate the differences in the meantime. In the new version of the development, data flow changes will no longer affect the entire system, as long as the EDI translation layer to modify the data flow and data dictionary definition can be. In the system design, targeted at the right in different enterprises, but the same or similar business process systems, as long as the developers for enterprises to make the different data definitions, while the application part you do not need to completely re-developed. Also in XML development, but also through XSL to make the interface and data separation, through the level after the separation, ERP system designers can focus on the process of ERP systems, but from a specific data-processing work, get out, so that not only reduces the ERP system development effort, but also to enhance the system's flexibility, customized ERP system for enterprises will be more difficult to reduce, for improving the success rate of ERP implementation of a great role in promoting.
As an information system design, a data solution, using data layer, the system designed to deal with the practice of separating layer allows developers to focus on their own modules, greatly improved work efficiency.*#However, since the process of data processing data received from the database and user data to be sent by the EDI translation layer to convert, this will reduce the data processing efficiency. In the ERP information system, in general, the data processing speed is not a bottleneck in the system, and ERP systems are typically deployed within the enterprise network, network speed and system conversion speed processing speed of the system, do not cause great impact. Compared with its benefits, which are acceptable. This approach for the development of common ERP system, particularly evident in the meaning.
Conclusion
ERP system integration is an important project, not just data integration. This article aims to propose a cross-system, cross-database data integration programs, data conversion through ebXML different types of data into XML data format available to the system in different data formats in the system identification problem by the ebXML registry to solution.
