Abstract
A database application generation system, Data Base 4th Generation Language (DB4GL), incorporating an object-oriented self-describing data model, has been developed at Sheffield City Polytechnic, UK. A recent extension to the DB4GL research has been an investigation into a possible parallel implementation of DB4GL on transputer hardware, and a prototype Parallel-DB4GL (P-DB4GL) system has been designed and implemented. The paper briefly describes both the original DB4GL system and the prototype P-DB4GL implementation, and a classification of object-oriented database approaches is presented. Results obtained from the prototype P-DB4GL are reported, and based on these results, directions for further research are discussed.
