摘要
本项土地管理数据库结构的设计是基于实体模型,并考虑到安全,系统根据不同的用户赋于相应的权限防止误操作和人为破坏。在VB环境下利用自身提供的数据库设计工具实现控件与数据库字段的联结,通过ADO实现系统与数据库的通讯、内嵌水晶报表控件实现打印功能。
In order to manage the land resource effectively, it is necessary to build Land Management Database System(LMDS). The design of LMDS can be accomplished easily by the mighty Oracle database. Visual Basic (VB) not only provides friendly development interface to users, but also possesses the powerful design tool of database. With ADO, LMDS can perform visiting and operating Oracle database in VB environment. With the experience of practical developing program, this paper introduces the design of Land Management Database based on Oracle database and illuminates the process of developing LMDS based on VB. Furthermore, it discusses some crucial technology.
