Обсуждение: Migration from PervasiveSQL
Well, the subject says it pretty well but to elaborate: I have a database from our ERP package that uses btrieve (PervasiveSQL) for it's database engine. I'd like to transition all of the data to PostgreSQL. I've been having trouble finding a suitable program to automatically get all of the data transferred over. I have the proper DDF files and an ODBC link in place to the data. Maestro DataDump (from the Postgresql Data Wizard program) only locks my machine up and it seemed to be the only think I could find that would take an ODBC link to the btrieve data and use it to extract the table defs and data to postgresql. Is there some other utility I could use or am I stuck writing a custom program to do it? I could maybe extract the btrieve data to CSV files but I don't have any easy way of doing that quickly for so many tables (and there are a lot!) Any help would be appreciated. Thanks!

There are many ways to do this of varying quality, mostly pretty dubious. In the microsoft world you have DTS which has an ok migrator. merlin

The OP stated he already had ODBC connectors setup.

I'm basically just writing a little something myself that uses the existing Pervasive and Postgres tools as much as possible. On a side note, not that it surprises me but it is a little weird that Pervasive supported postgresql for a while but yet there is no really good way to convert from pervasive to postgres. I've always thought that Pervasive backing out had a lot more to do with them suddenly realizing they were showing the world a better product than theirs and not because of the large amount of support postgresql already had (like they claimed the reason was...)
You might take a look at BtSearch at www.nssdd.com. It will allow you to export all the Btrieve files in a DDF to CSV format. Gil

I see the figure of the application business used realized with two or more databases. Then, I have explored the solution method which does not spoil those property. Probably, ORACLE, DB2, SQLServer, and PostgreSQL live together. On that occasion, They wish data to flow smoothly between those databases.
