Database management currently assumes a relative stability of database structures and supports user viewpoints through a number of views. New users must either adopt their data demand to existing views or issue a request for support of their demands. The support for the second option is not feasible whenever user communities often change or users agile change their viewpoints. Further applications continuously evolve. This evolution also results in change requests to database structures, to database views and to database features.
