Abstract: On the basis of the request of a product data management(PDM) system for a flexible coding system,an analysis on the principle of flexible coding system oriented multi-view showed that the code should be emphasized to be generated and used under definite certain contexts.Architecture of flexible coding system oriented multi-view is studied,and its class diagram of implementation for the system designed.It can support the establishment of five kinds of code segments,provide the tools of flexible definition as well as coding rules,and can drive the auto generation of object coding under different views(contexts).On the foundation of the characteristics of systems,part-coding are taken as samples to validate and elaborate the flexible coding oriented multi-view process.
