I am doing a study into optimised architectures for real-time database engines which may or may not use distributed techniques and/or parallelism. I would be very interested to hear from readers of this newsgroup, as to what they think the main characteristics of real-time database subsystems are. Do you have any experience in implementing real-time databases ? What were the main requirements for the database function of the system ? In order to get a sensible frame of reference for this subject I should explain what type of real-time system I'm considering. Large, complex real-time control systems for example in chemical control plants; or C3 (command, control, and communications) systems in naval vessels are my main area of interest. With the later, C3 systems being my primary source of information. The most obvious characteristics of the database function of these systems match the general requirements for the whole system i.e. high performance, reliability, expandability, graceful degradation under hardware/software failure etc. What though are the specific characteristics of the database and DBMS and what makes them different from commercial non-real-time databases and DBMSs. Any information would be greatly appreciated. Phil M Sleat JANET: phils@uk.ac.city.cs

I am looking for references to real-time databases. In particular does anyone have details of any case studies?
