A database server for distributed real-time systems: issues and experiences

The design and implementation of database systems for real-time applications presents many new and challenging problems. In addition to maintaining data consistency, the database system must satisfy timing constraints associated with transactions. In this paper we present our experiences in integrating a database server with a real-time operating system kernel and our attempts at providing flexible control for concurrent transaction management. We chose the ARTS operating system kernel as the basis for the real-time database server. Current research issues involving the development of a programming interface and imprecise computing server are also discussed.<>
