OLE DB allows you to develop applications that access diverse data sources , whether they are DBMS or not . DBMS程序能够让你从数据库中抽出,修改或是存放信息。
7
The DBMS ensures that the index is always consistent with the data in the table by updating it during INSERT, UPDATE, and DELETE operations. 通过使用INSERT、UPDATE和DELETE操作对索引进行更新,DBMS能够确保索引始终与表数据一致。
8
DBMS automatically fires the trigger as a result of a data modification to the associated table. 当关联的表发生改变时,DBMS自动激发触发器。
9
If there is no index on name, the DBMS does a full table scan and applies the toUpper function on the name column for each tuple. 如果没有为名称建立索引,那么DBMS将执行全表扫描并对每个元组(tuple)的name列应用toUpper函数。
