I have two files that I need to get information from. One ends with extension '.odb' and the other ends with extension '.odx'

Any ideas for a program that could open or read these files? I don't know a lot about databases.

I did a google search for .odb extension and found several possiblities, the most likely seemed to be the open office suite. But I tried that and it wouldn't open the file.

Any help on where to look would be great.
