From relations to objects: A translation methodology for an object oriented front-end to RDBMSs

The operability of information intensive applications relies heavily on their ability to acquire, maintain and store complex information entities pertaining the particular data domain. The present paper addresses the resolution of availability problems in a front-end aiming at the development of database applications. In particular, within the presend paper we elaborate on a general purpose methodology for gaining information from a persistent information repository whose storage formalism is based on the relational model. Through the presented methodology, the information gained from the information repository is transformed into a form which fulfils the operability requirements of the developed front-end. Accordingly, the presented methodology also provides for transparently mapping the manipulated information back to the persistent repository, a fact that guarantees persistency for the objects manipulated at the level of the presented front-end.
