Having worked extensively with Btrieve/Pervasive databases for over 20 years, I know virtually all aspects of creating, extracting, manipulating this data. Whether you have field level definitions (ddfs) and interact with the data using SQL or rely on the old record-at-a-time retrieval, I can help. Performance an issue? If we can understand how you use your (new or legacy) applications, we can help tune even very old databases to improve performance. Pervasive is supposed to be set-it-and-forget it. Well, sort of. Even though Pervasive doesn't need day-to-day monitoring, checking the health, removing old or spurious data, and compacting the database can often help a sluggish system regain lost speed. We are also a C#/.NET/SQL Server shop and have a substantial code-base and expertise to draw on for both off-the-shelf or custom programs. We are located in the US. Pacific Time Zone
