C-ISAM data mounted/loaded into MySQL?

Greetings,

I am working with .dat and .idx table files powered by C-ISAM for a proprietary system. These files are not readable plain text for the most part.  Is it possible to mount these in MySQL in their current file format?  I see that C-ISAM is specific to Informix so am I correct in assuming there isn't a C-ISAM specific engine I could load into MySQL?  

If getting the data to list in MySQL is possible how would I go about doing this?

I have searched in the forums and a bit on the web, similar questions were asked but no answers provided.

If there are any data experts out there I would appreciate any guidance, even if it is a well informed no.

Thank you.

I'm not sure about mounting anything in MySQL. Is that essential to you or do you just want access to these data using a suitable tool such as VB or ODBC?

C-ISAM is a pre relational storage mechanism, basically a set of API's you called from C to read/write data. Informix used C-ISAM as the underlying technology for their first RDBMS, called Informix SE (still available). BTW if you see some .sys files alongside the .idx and .dat files then you have an Informix SE database.

There's a good discussion of this topic here

There are people claiming to give ODBC access to C-ISAM

If you could have ODBC or similar access to the Informix data would that help you?

R,

Those first two links I have previously visited.  I am still trying to grasp the whole situation, however it appears I am working with raw .idx and .dat files.  No .dbs or anything that seems to tie them together.  

I will try to wrestle with just being able to view the data with the Easysoft trial.  However if there is some option with MySQL or an eventual migration possibility I would be interested to hear about it.

If no one has anything else to add about other options I will consider your response a solution.

Thank you for your reply.

Hi guys,

I have a dump of .dat and .idx files from a C-ISAM database on my windows machine. I would like to read these files. Are you aware of any tools or solutions that can read these files or structure these files so that they can be readable?

Thanks
