Description
Technical field
The present invention relates to the data interaction technical field between heterogeneous PDM system, particularly the data interactive method between a kind of heterogeneous PDM system.
Background technology
PDM (Product Data Management, product data management) is all information relevant to product of management (comprising electronic document, digital file, data-base recording etc.) and a technology all and process (comprising workflow and change flow) that product is relevant.PDM system provides the information management of product lifecycle, and can be for the Collaborative environment of a parallelization is set up in product design and manufacture in enterprise-wide.
PDM system is a kind of instrument that helps user management product data and R & D of complex.PDM system is guaranteed tracking of products design, is manufactured required mass data and information, and supports thus and maintenance items.From product, PDM system can help tissue products design, improves product structure and revises, and follows the tracks of the design concept in progress, finds out easily in time archive data and relevant product information.From process, PDM system tunable is organized in the whole product life cycle process events such as criterion design review, approval, change, Workflow optimization and product issue.Because PDM system is improving enterprise efficiency, the outstanding performance that improves enterprise competitiveness aspect, PDM system is obtaining the favor of increasing enterprise personnel.
Traditional PDM is data-centered closed system, and the data interaction between different PDM systems need to be carried out special secondary development, and this PDM system is mainly used in inner enterprise.Management system under agile design pattern relates to multiple outside enterprises, and multiple management of product design systems will be carried out alternately.But different systems is used the identical things in different terms and conceptual description design management field.Along with the accumulation of data cell in database, it is very difficult that processing, extraction and swap data become.By the data integration form of standard and the standardization of product information model, realize the data integration of heterogeneous PDM system, the information of product in whole life cycle can fully be shared by enterprise.
Distributed PDM system is conventionally from different software suppliers, even if use the identical PDM system of same software supplier, the process difference of each corporate client, these factors all can cause the PDM system of different enterprises to there are differences on to product data information model representation, and the PDM system that different enterprises are used is heterogeneous PDM system.Owing to lacking the support of product data integration standard of unified PDM system, this causes cannot mutually exchanging and share the product data that design between the PDM system of different enterprises.
In the integrated solution of isomery PDM application data, there are many technology and product, can be used for making data and logic between system to form integrated.Although, in many solutions, all use integrated between automanual Realization of Product system, for most of technology, except needs use COTS product, also need to carry out a large amount of complementary engineering development work.By the data that use in a system being converted to the data that can be used by another system, thereby on data level, carry out mutual.
