Integrity constraints and structural modelling in object-orientated databases: a unified approach

摘要

Database technology is constantly evolving, with the aim of sup- porting larger and more complex applications. To this end, more powerful database models have been recently introduced. Along this line, Object-Oriented Databases (ODBs), characterized by rich data and behaviour modelling facilities, appear to be the successors to relational databases. In this paper, we propose to extend the data modelling component of ODBs, to declartively represent semantic integrity constraints in the database schema.
