Managing Contention and Timing Constraints in a Real-Time Database System

Abstract

Previous work in real-time database management systems (RT-DBMS) has primarily based on simulation. This paper discusses how current real-time technology has been applied to architect an actual RT-DBMS on a real-time microkernel operating system. A real RT-DBMS must confront many practical issues which simulations typically ignore: race conditions, concurrency, and asynchrony. The challenge of constructing a RT-DBMS is divided into three basic problems: dealing with resource contention, dealing with data contention, and enforcing timing constraints. In this paper, we present our approaches to each problem.
