摘要
在STEP标准的应用中, 常需要通过不同STEP应用协议之间或其中某一应用协议的不同视图之间的映射来实现异构系统间的数据交换。本文提出了一种实现STEP模式映射的实用方法。依靠建立(AP203+PDMschema) 扩展的内存模式, 通过实例映射器, 实现了AP203到PDMschema模式的数据转换。
In the applications of STEP standards,the data exchange between heterogeneous systems is usually needed for schema mapping between different STEP application protocols or between different views in a special STEP application protocol.A practical mapping method was proposed to perform the mapping between STEP schemas.An extended combined schema,AP203+PDMschema schema,was built.By an instance mapping tool,the data exchange between AP203 and PDMschema was realized.
