Background:

Objects are crucial in database and artificial intelligence research.
Existing systems lack efficient integration between relational databases and expert systems.

Purpose of the Study:

To present a novel object-based architecture for expert database systems.
To enhance the interaction and data manipulation capabilities between databases and expert systems.

Main Methods:

Developed an object-based interface mapping relational data to object templates.
Created object networks representing different database views.
Implemented processes for template instantiation, caching, navigation, and updates.
Utilized a semantic model for automatic relation mapping.
