Proposed Framework wWhich Use the Object Oriented Principles in Relational Systems. General Aspects and Principles (Part I)

There are some significant theoretical and technological approaches on the issue of object-relational "impedance mismatch" between applications' abstract model and database structures. Two characteristics of those approaches we think that are questionable: first of all it is so called “flat†nature of relational systems and model, and then there is the drawback of the storage of (object oriented) semantics on the application level, thus severe limiting the data (object) sharing and, at the same time, virtually broking the data independence principle of database systems architecture. In this paper we will try to outline an approach to address to some in a concrete manner.relational data structures design, object oriented principles, SQL3, UML, MDA.

Proposed Framework which Uses Object Oriented Principles in Relational Systems: Structure and Formating (Part 2)

Our approach tries to overcome the limitations of so called “flat nature†of relational systems, in the actual context of actual relational database theories, database systems technologies and object oriented methodologies by proposing an MDA framework to map an object oriented (UML formalized) model to object-relational structures of today’s database systems.relational data structures design, object oriented principles, SQL3, UML, MDA.
