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 moved together with the database.
