STRIP: A Soft Real-Time Database for Open Systems
Department of Electrical Engineering, Stanford University

Traditionally, real-time databases have been embedded in control applications, such as plant control and flight control. Currently, however, there is interest in soft real-time data management for other types of applications. Many problems in program trading, telecommunications, and multimedia delivery require systems that are cognizant of the temporal aspects of both data and transactions.

In such applications, the real-time database is just one component in an open systems consisting of many heterogeneous databases, and the flexibility to deal with unpredictable situations and the ability to cooperate with other databases (often non-real-time databases) are just as important as the guarantee of stringent timing constraints. In this talk, I describe a database system designed explicitly for heterogeneous environments, the STanford Real-time Information Processor (STRIP).

STRIP, which runs on standard Posix UNIX, is a soft real-time main memory database with special facilities for importing and exporting data as well as for handling derived data. I will describe the architecture of STRIP, its unique features, and some of the interesting problems encountered in its implementation. The motivating example will be database support for financial trading floors.
