Originally I had developed this application for the Berkeley DB but they wanted an outrageous amount of money for licencing since we were using transactions. Memory and disk weren't really constraints when I re-developed it. Time and cost were constraints though and MySQL was the fastest thing I could get running on QNX.

But you still have to put the MySQL tempdir someplace and that may still get some read/write activity. Of course if you are just doing data collection then this should be minimal. MySQL is pretty elaborate for something like this. So I'm wondering if MySQL because of its disk activity is the right database for the job? There are memory based databases that are excellent for this type of application. They are small and extremely fast and can load/save the table to disk and you can eliminate all disk activity. The one I'm thinking of is called TkbmMemTable and runs in Delphi and I think there is a Kylix version for Linux. It has built in compression, indexing, blob support, and it is free (they have a pay version) and there are no royalties.http://www.components4programmers.com/products/kbmmemtable/ This means there is zero disk activity and the "database" (which is a flat file system) and it gets compiled into the .exe file so there is a zero footprint install. You can then export the data to a CSV file for import into another database. It is also possible to access the database over a webserver too so you can access the data remotely. Send me an email if you want me to send you a compiled TkbmMemTable demo app if you want to see what it can do. (for Windows) -I'm not associated with their company but I've been using it for years and it's great. </QUOTE> -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
