How do you tell what language a database is written in. For example, the database I am dealing with has a main folder with tables with the extension .dat no data in this table though. But there is a secondary folder with files containing the actual data with extensions of .dat and .idx. These files do not represent a table layout at all. What I would like to do is create .idx file and .dat file with my own data that I asuume would populate the actual table when the call is made to open the database I need. hmm does that make sense at all? Any help determining what code language I am deeling with would be great.
