Abstract : Database management systems have historically been the domain of large mainframes. However, the popularity of mini and micro-computers has spurred the development of database systems appropriate for those devices. Concurrently, database systems design is turning away from traditional hierarchic and CODASYL models to embrace the conceptually simpler relational database approach (1,2,3,4,). The relational database approach views data as being in tables. The entries form the rows and are called tuples. The columns are called attributes. Simple selection commands are provided to search for entries with attributes of a given value. Other commands allow the extraction of a subset of entries (found by the selection commands) and the incorporation of that subset with others. This approach is not as efficient as the traditional model in its implementation but offers far greater flexibility in the incorporation of data and the ability to 'explore' the data base. This report documents the attempt the develop a relational database management system for the Harris Minicomputer at Florida A&M University.
