| Abstract: | 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. With this method, the speed of creating and searching database will be increased. Effects are good in sevelal CAPP systems. |
