Abstract (en)
[origin: WO9909494A1] Software methodology to enable "legacy" relational database co-existence with an object database in an object oriented system. This comprises a declarative relational to object schema mapping process which is implemented during development and a query engine which makes use of the mapping at run-time to allow access to data in the relational database by object oriented access methods. The methodology allows access to data in the relational database in the same manner as access to the co-existing object database, that is without embedded SQL code, to provide data location transparency from the application developer's viewpoint. Application of the methodology to the JADE<TM> object oriented development and run-time environment is disclosed.
