面向PDM系统的事物编码模型及其建模实现

提出了一种面向信息管理和高效检索的“四段式”事物编码模型，该模型能够与PDM系统中的分类管理模块功能相得益彰。对编码模型的UML建模则使模型的可操作性更趋于实际，从而为企业信息化过程中的事物自动编码提供更直接的参考。实际工程应用表明，该模型具有高度的柔性、紧凑性和通用性。

PDM-oriented Object Coding Model and Its Implementation

Since information technology is more and more popular in enterprises, the functionality of the object coding has been switched from classification to identification. Therefore, a new object coding model which makes engineers access product resources more efficiently was put forward based on the requirements come from PDM implementation in an air compressor manufacturer. This model has been mapped to a logical model using UML which can be viewed as a reference model for automatic object coding in an information management system. A case study was also discussed to prove the commonality and flexibility of the model.
