Hello. I need some information about real-time databases. I am currently working on a realtime process control project. I have to have a real-time database to store real-time data. Any information would be welcome. H. Wang wang@cs.utoronto.ca

what type of operating system are you working with???? pc-based??? i am somewhat familiar with process control under qnx, and it seems that db-vista has been what people are using there with good success.

I don't know much about it personally, but I have seen a data sheet for HP Real-Time Database (HP RTDB). Some particulars plagiarized from the data sheet follow: HP Real-Time Database (HP RTDB) Product Number 92572A - Development Copy 92572E - Right to Execute Runs on HP9000/800s and /300s Provides software application developers with a flexible tool to structure and access memory-resident data in industrial automation, telecommunications, and other very high speed applications. It is a library of routines used to: o Define or change the database schema and events o Build the database in memory, load/unload data o Read/write data from/to the memory-resident database o Backup schema and data o Archive data with time stamp and header information It also has an interactive query facility to configure the database, aid in debugging applications, and execute command lists. RTDB is one of HP's Industrial Precision Tools. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Edward McClanahan Hewlett Packard Company Mail Stop 47UP -or- edwardm%hpda@hplabs.hp.com 19447 Pruneridge Avenue Cupertino, CA 95014 Phone: (408)447-5651
