Abstract: On basis of the notion of a semantic database, and by utilizing the theory of Information Management Systems, we study the schema concept in a relational database and give a formal description of the schema handling implied by operations of relational algebra. Our frame-work presents a natural conceptualization of database schemes, independent of the actual design model, and enables further investigations to be made on a formal ground.
