ABSTRACT	Since real world databases are known to be very large, they raise problems of the access. Therefore, real world databases onlycan be accessed by database management systems and the number of accesses has to be reduced to a minimum. Considering this property, we are forced to use standard set--oriented interfaces of relational database management systems. We present a system for discovering data dependencies, which is build upon a set--oriented interface. The point of main effort has been put on the discovery of domain restrictions, unary inclusionand functional dependencies in relational databases. The system also embodies an inference relation to minimize database access. 1 Introduction Data dependencies are the most common type of semantic constraints in relational databases which determine the database design. Despite the advent of highly automated tools, database design still consists basically of two types of activities: first, reasoning about data types and data dependencies and...	user correction - Legacy Corrections
