FIRM-a database management system for real-time avionics

The Functionally Integrated Resource Manager (FIRM) is an object-oriented database management system (DBMS) for use in avionics applications. It is also suitable for other real-time embedded applications from submarines to space stations. This paper examines the need for FIRM, and the unique requirements for avionics DBMSs not met by ordinary DBMSs. It then describes the unique features and construction of FIRM which allow it to meet those requirements.
