Question: At my work, my co-workers are considering using hyperfile as a database server for a windev project. I don't even know that kind of database, it's from PCSOFT, the company that develops windev.

Since windev can also work with microsoft sql server, I'm looking for advice on that kind of database (performance, stability, etc) from people who already used it.

Regards!

Answer: 
You should carefully consider what sql functions you will use. For example deg2rad, rad2deg, ... not working correctly.

Also if you want to use it on a mobile device (Windev Mobile for iOS or Android) you should use SQLLite. Because HyperFile uses a lot of memory and it will be a problem on mobile.
FYI: New in Windev version 19: Hyperfile SQL is ACID.
