基于 Client/Server 工艺数据管理

Data Management for Process Planning Based on a Client/Server

提出了一种基于ＶｉｓｕａｌＦｏｘＰｒｏ３．０客户／服务器的工艺数据管理方法，论述了利用ＶＦＰ３．０最新的数据库技术对工艺数据进行组织、管理，以及利用事务处理机制实现工艺数据安全恢复等方面的关键技术．介绍了工艺数据库管理系统（ＰＤＢＭＳ）的系统结构．

This paper presents a method of process data management based on the client/server of Visual FoxPro 3.0 (VFP 3.0). The utilization of the newly developed database technology of VFP 3.0 to organize and manage the process data and the key technical problems such as the realization of safety and recovery of process data with the transaction mechanism are discussed. The sharing strategy of the multidata base based on ODBC standard and the architecture of a data management system for process planning (PDBMS) as well as the methods of data acquisition and data submittal using SQL statement through a local area network (LAN) are also discussed.
