Abstract
We notice a data-modeling gap in current database business applications: the emerging data modeling paradigm for computation is object-oriented, while the incumbent data models for storage are mostly relational or hierarchical. The gap originates partly in the reengineering of applications and of databases, that do not proceed at the same pace. But it is also likely to be typical of heterogeneous systems in highly distributed software architectures. We propose a mediation service called Object View Broker, that provides object views of data stored in relational or other databases, to object-oriented applications. The Object View Broker manages these views in a multi-application, multi-databases environment, and provides customized services such as notification, caching and locking. We have implemented and used a version of Object View Broker for a service order distribution application at US WEST.
