摘要
研究工艺数据库中工艺资源即各种静态数据和动态数据的组织方式,提出了一种将数据源合理的组织成表的方法及在关系到数据库系统中拆分多维表的方法;应用数据仓库的概念组织数据和表的存储格式并给出了数据库中表与表之间的关系模型.该方法和技术可以大大提高建库速度和查询的效率,在几个CAPP系统的应用中,效果良好.
A method for managing dynamic and static data in process planning database is proposed. How to group data source into tables and settle multi-dimensional tables in relative databases are put forward. The conception of data-warehouse is used to manage the model of saving data and tables. The relations among tables are illustrated.
