Dave,

Do you need dbase files or can just be another format?

I am converting an old system that has dozens of tables, 50 or so custom written programs and semi-associated systems. I am moving little pieces over to PostgreSQL a little at a time because it is way to much to move everything at once. The old design needs to be reworked and has been reworked over the years by way to many system designers.

I need to be able to retrieve and update records in the old system and at the same time manipulate data in the new PostgreSQL system. I want the front end to become congruent and transparent to the two data storage backends. As time goes on everything will be in the PostgreSQL backend but for now...

Dave


 You can use serendipty library. It will not give you SQL but it will give you those old school feeling using record pointers and navigation. Also, if the problem is in the deployment you can always check Valentina or wait till SQLite external is available, both will give you nice SQL features.

Also, try doing windows in Python... it's awfull even using PyObjC... 
Better use Rev. So the point is, it must be *.dbf files, like you want to migrate old records, or it must be a simple filebased database with no fuss?
