| 摘 要： | 分析基本数据库的依赖关系。数据库及其环境的复杂程度决定了依赖关系的复杂程度。当一个数据库被移到一个新的服务器环境中,原有的依赖关系必须相应地移过去,并与新的数据库结合成一个整体,这样才能保证新的数据库系统不会因为环境的变化引起依赖关系的断裂式消失,从而使其不能正常工作。

| Abstract: | This paper analyses the dependent relationship of basic database. Dependency covers implication and optimization database problems related to logical constraints,commonly called dependencies. It also deals with relationship between a database and other entities outside of the database. When the database is moved to another server,all of its dependencies should be carried over in order to make the relocated database run successfully. The paper examines different types of dependencies and shows how they are m... |
