【摘要】 用Delphi开发数据库应用程序时,如果程序中数据访问代码发生变化,需要重新编译并更新应用程序,烦琐且易出错.把主程序与数据访问部分代码分隔开,把与操作数据库相关的部分做成DLLs,当用户对数据操作的需求发生变化时,修改DLLs的相关代码并将该DLLs拷贝到使用者处,这样可及时满足用户需求,不断完善程序功能,也便于更新版本.更多还原

【Abstract】 When delphi is used to develop a common database application,these data module controls are brought other data forms to program and carry out the operation of data access.In this case if the data code changes,program must be made again.At the same time the programs of the users should be improved.In this system,the main program is separated from the part of the data access,the data access just need to be programmed again.the data access can be made into the DLLs.If the program changes,the DLLs can be copied.It is easy for the users to improve the edition.更多还原
