As a free lance computer consultant, I am working for a local store.

They have an ancient point of sale (POS) system that has a server and several register machines, all running on a SCO unix. The system is at least 10 years old, maybe 15.

The the POS vendor discontinued the product (Chainware) some years ago. The client has some date mistakes that they want me to correct and to help them move the system to a new POS. To do that I need to get into the database, obviously, and figure out the structure.

Doing a strings of one of the executables didn't reveal any usful information. The development package isn't installed so I can't use ldd or nm or other tools to determine what libraries are being used and thereby what type of database I'm dealing with.

The POS database files end in .df, .dsc and .idx.

Does anyone have any ideas what type of database this is and/or tools for opening and modifying it?

Many thanks!

Try "ps -ef" to see if you can identify the database engine process names.
The content of $PATH might help.
Copyright notices in startup scripts?
Any support documentation?
