ERP and PDM Information Integration Analysis
ERP and PDM integration Model
Through the integration of the contents of the two systems and systems analysis of the cross-section, combined with enterprise applications are now some domestic situation of the two systems, we propose the following four types of integration patterns:
(1) Application integration package. Packaging is to the object properties and operations methods encapsulated in the definition of objects at the same time. Because encapsulation, when the program design to change an object type expression of the internal data structure, you can not change the object type in any program to work, "packaging" the data and operation of a unified management interface. PDM through the CORBA specification can enhance scalability, and ERP systems integration capabilities. OMG (Object Management Group) are being developed CORBA-based PDM Enabler (PDM-enabled component) standard specifies the function of the PDM system, PDM system, the logical model and the PDM interoperability between products, and can enhance scalable PDM and with the ERP system or other application systems integration capabilities. Follow the standard PDM systems capable of a PDM system's data to another PDM system, and implement application systems federation mechanism, namely the PDM to manage ERP applications, system or another PDM system data. At the same time, through the specification of the objects defined in a unified interface, CAD, CAM can call these objects defined by the service interface, without corresponding attention to the specific products, thus greatly facilitate the system integration.
(2) Through schema integration. Since PDM systems and ERP systems are the underlying relational database, product data are stored in the database, the respective domains, through pattern is two systems can operate on data in the database, and exchange data. PDM system should be as far as possible the data stored in the ERP system database, which enables the two systems share the true databases can be fully integrated with all ERP components in the PDM system, both systems use the same data model and data.
(3) An indirect schema integration. This integration is the PDM and ERP systems need to exchange product data and related documentation in accordance with a unified document format and interface requirements for storage, PDM and ERP systems through their compiled data import, export interfaces to achieve the two systems of information exchange. When designing new products or modifications of old products, the relevant data will be automatically rendered in the ERP system, ERP system can at the same time consistent and the new file formats sent to the PDM system. Typically, this integrated model of support for common data exchange standards such as STEP, XML and so on. They provide a specific application systems do not rely on a neutral mechanism, used to describe the entire product life cycle data.
(4) Tool schema integration. PDM and ERP systems have developed their own database access tools for the exchange of information between the two systems. Between the two systems must be in accordance with their system data interface types of requirements, to provide to the other system, the appropriate tools to access the database. Product configuration in the PDM system, human-machine interface, you can enter a product based on user requests configuration data from the PDM automatically configures the corresponding product bill of materials. ERP systems can be developed through their own PDM system data access procedures, read the PDM system to produce a list of materials data, re-transmission sent to the ERP system, the product structure tree. |
