Software Architecture for a Firm Real-Time Database System

An actual development of a real-time database management system (RT-DBMS) must confront many new and practical problems which have been often ignored in previous work based on simulation. In addition to transaction scheduling, an RT-DBMS must deal with resource and data contention and enforce timing constraints. This paper discusses how current real-time technology has been applied to architect an RT-DBMS on a real-time microkernel operating system and how the problems have been addressed. We present the current software architecture of our StarBase RT-DBMS and address how it can be extended to support both guaranteed and non-guaranteed transaction processing. keywords: real-time database systems, real-time transaction processing, concurrency control, predictability 1 Introduction As real-time applications grow more and more complex, so do the ways in which they maintain and access data. As programs are required to manage larger and large volumes of data, they typically turn away fro..
