This report reviews the object-relational model in the context of object-oriented and relational databases. The object-relational model is described in detail with particular emphasis on the Postgres data model as produced in work at Berkeley. There are many interesting application areas which can be looked at using Postgres, including those involving complex objects and active databases. The main work reported here is on the use of Postgres for running an administrative database for student records with extensive derived functions to calculate a variety of summary data. A preliminary evaluation of the Postgres system is given.
