Abstract

Many applications, such as telecommunication, process control, and virtual reality, require real-time access to database. Main-memory DBMS, which becomes feasible with the increasing availability of large and relatively cheap memory, can provide better performance than disk-based systems for real-time applications. This paper presents an overall architecture of M/sup 2/RT, a main-memory real-time DBMS, and an object-oriented design of its storage system called M/sup 2/RTSS. M/sup 2/RTSS provides classes that implement the core functionality of storage management, real-time transaction scheduling, and recovery. Implemetation-specific information is encapsulated in these classes and extensions can be made by inheritance. With object-oriented features, M/sup 2/RTSS can easily incorporate new development in application requirements and the result of ongoing research in real-time systems.
