Abstract

Our goal is to make the data in the database more accessible to end-users. We introduce a new data model, called MIX, which incorporates the concepts from semantic data models such as entities, ISA, aggregation, characteristic property, and shared property hierarchies into the universal relation data models (URM) to model a database in a top-down modular way. We then show how a consistent URM style's language can be provided for both database retrievals and database updates. The database schema graph of this model further facilitates us to implement an integrated graphic user interface for the database system design life cycle.
