Database Management Systems represent important tools for professional applications of inter-connected workstations. This paper presents the integrity subsystem of such a DBMS. Private and shared data are distinguished, as well as an original and possibly several duplicates. It is shown which kinds of integrity constraints across the borders of private and shared data are possible, and a data definition system is described which guides the user towards a complete definition of integrity constraints. For this purpose, the design methodology for an extended relational data model is adapted. The implementation of the concepts presented within a prototype federative database server system is described.
