I would not do that. Most RT applications will be doing straight data capture from a few (usually one) sources and you will not share it with anyone else. Speed is the most important thing in RT applications, while data integrity, sharing, etc. are what is important in an OLTP application.

Stuff your data into a file in your RT/OS, scub it, then move it over to an analysis tool or a database later. Received on Mon Jan 06 2003 - 17:29:12 CST
