Federation and Stepwise Reduction of Database Systems


Many enterprises su er from the problems of heterogeneous data base systems such as redundancy and lack of control Existing approaches either try to couple the database systems into a federation FDBS or migrate data to a single often new database system This paper proposes an integration of both concepts by incorporating migra tion facilities into an FDBS General FDBS concepts couple the multiple database systems and allow several degrees of global control over het erogeneity and redundancy In addition new migration concepts enable data and applications to move from one component database system to another This supports the requirement of industrial users to stepwise reduce heterogeneity and redundancy in a controlled way It allows to decrease the number of database systems as much and as fast as the enterprise areas can bear it
