An automative file design aid is proposed. The aid will generate a conceptual view of the data by merging user's functional views. A directed graph is used to represent the relationships within the conceptual schema. The procedure will input user relationships and convert the set of relationships into a conceptual schema. The functional view is represented by the hierarchical model, while the conceptual view utilizes the relational model.
