Abstract

<p>This paper provides the outline of database and metadata design process, and emphasizes the importance of conceptual modeling (i.e., conceptual design) in the process. While taking up practical examples, it explains 1) the conceptual modeling using the Entity-Relationship model, and 2) its subsequent logical and physical design steps, that is, 2a) database schema design using the Relational data model and 2b) metadata schema design including the decision on its record structure and data elements, both of which schema are converted from the conceptual model built on in the preceding step. In particular, the importance of conceptual modeling, which clarifies components and their relationships building up the universe of discourse and requirements satisfied by implementing the database and metadata, is emphasized.</p>
