Delphi中实现数据库备份的方法与应用

Database Backup Using Delphi and Its Application

在数据库应用系统中 ,常常要对数据库进行备份。数据库备份包括数据库结构备份和数据库数据备份 2部分。对于数据的备份主要是成批的复制、追加、删除和更改等操作 ,这种批量操作在专门的数据库开发工具中是利用APPEND和COPY等命令带上相应的命令子句完成。但在其他开发工具中并没有类似的命令 ,而是提供能完成类似功能的控件或对象 ,如在PowerBuilder中就是利用数据管道来完成 2个或同构或不同构的表之间的数据批处理。

A database needs to be backed up in its application. A database backup is composed of its structure backup and data backup. Batch operations, such as copy, append, delete or edit, are used to realize database backup. These batch operations are achieved by using APPEND and COPY commands together with some relative commanding clauses in specialized database development tools, while in other tools, there are components instead of corresponding commands to realize database backup. This paper discusses how to use the TBatchMove components in Delphi to realize database back up.
