Abstract :
A data processing model called PIM is proposed. This model has its own database diagram mechanisms and a visual data manipulation language is defined on the diagrams. The visual language allows users to construct database queries utilizing iconic pictures over database diagrams. The algebraic capabilities of the language in query processing are described, and a formal definition is given. Related systems are reviewed, and the distinct features of the present system are highlighted
