Abstract Functional dependencies (FDs) and inclusion dependencies (INDs) are the most fundamental database integrity constraints, and they are used in many data models. In a previous paper, we described a synthesis algorithm for the design of a relation database from FDs. In this paper, the effect of unary inclusion dependencies (UINDs) on the relational database design is studied. Though the implication problem for a set of INDs and FDs is undecidable, if attention is restricted to unary INDs, there will be a complete axiomatization and its decision problem can be solved in polynomial time. To discover new FDs and INDs from a set of FDs and UINDs, an effective algorithm is presented to find k-cycles in the multi-graph presentation of FDs and UINDs. Finally, the synthesis algorithm is enhanced by considering interaction between FDs and unary INDs.
