Object Wrapper: an object-oriented interface for relational databases

Most commercial applications have to cope with a large number of stored object instances and have data shared among many users and applications. For object-oriented as well as conventional application development RDBMS technology is currently being used in most cases. We describe a software module called Object Wrapper for storing and retrieving objects in an RDBMS. Having these capabilities in a separate component helps to isolate data management system dependencies and hence contributes to portable applications.
