We present an abstract view of information integration based on a three dimensional (3D) space of Concepts, Data Models, and Domains In this view, the first dimension specifies the concepts (e.g., entity sets, relations, classes, etc), the second dimension defines the data model in which a concept is represented (e.g., relational, semi-structured, object-oriented, etc), and the third dimension determines the concept domain which relative to the universe of the model, uniquely identifies the application domain We also introduce three basic transformations, called X-transform, Y-transform, and Z-transform The queries posed to the integrated level can be expressed on the basis of these basic queries.
