Integration of a database system with real-time kernel for time-critical applications

Transactions in real-time database systems should be scheduled considering both data consistency and timing constraints. Since a database system must operate in the context of available operating system services, an environment for database systems development must provide facilities to support operating system functions and integrate them with database systems for experimentation. The authors chose the ARTS real-time operating system kernel. They present experience in integrating a relational database manager with a real-time operating system kernel and attempts at providing flexible control for concurrent transaction management. Current research issues involving the development of a programming interface and imprecise computing server are also discussed.<>
