Abstract(in English)	Today, we use diverse data, such as multimedia data, in our computer systems. A Database system that manage and store these multimedia data must be able to store and manage heterogeneous collection of data. In this paper, we describe a data model that manage a heterogeneous set as a homogeneous one if each element satisfy the condition that given for the set. The set specify a definition of the element type, and can have functions on the set that treat any element of the set as the type. Application programs that use data in the set allow unified access to elements of the set, that is it can access data as the set specified type virtually, where it know the real type of the element or not.
