Abstract
LOGRES is a new project for the development of extended database systems which is based on the integration of the object-oriented data modelling paradigm and of the rule-based approach for the specification of queries and updates.
The data model supports generalization hierarchies and object sharing, the rule-based language extends
Datalog
to support generalized type constructors (sets, multisets, and sequences), rule-based integrity constraints are automatically produced by analyzing schema definitions. Modularization is a fundamental feature, as modules encapsulate queries and updates, when modules are applied to a LOGRES database, their side effects can be controlled.
The LOGRES project is a follow-up of the ALGRES project, and takes advantage of the ALGRES programming environment for the development of a fast prototype.
