Active object oriented databases in control applications

This paper describes a unified architecture for control applications using an extended object-oriented database system with queries and rules. We specify the requirements that control applications demand on the database, and how they are met by our database system architecture. The database system, AMOS, is a main memory database that provides information sharing, powerful data access via an object oriented query language (AMOSQL), data independence, and reactive behavior by active rules. The application considered is a robot and manufacturing instruction system, ARAMIS, which is a task level programming system. The presentation uses a specific scenario related to manufacturing control.
