Software architecture for a firm real-time database system

摘要

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.
