STEP标准下的SDAI的模型与应用的研究

The Research of SDAI's Models and Application in STEP

产品漠型数据交换标准(STEP)规定了产品模型数据的表示、存取方法。该文着重讨论了STEP体系结构背景下的标准数据存取接口(SDAI)的模型定义,它的子模式:字典模式、对话模式、总体模式以及SDAI功能操作的确切含义和进一步实现的方法。提出了服务器端多个Server进程共同完成对数据和模式管理的实现方案。最后,给出一个应用实例供参考。

STEP describes the representation and the storage of the model of products' data. This paper focuses on the definition of SDAI's models, dictionary model, dialog model, environment model, and both the definition and implementation of SDAI's functions, providing a resolution to manage models and products' data, through the service of multi-processes at server end, and an example for reference.
