By Use Case
The CurrentWare Server is compatible with two types of databases – Firebird Server or SQL Server.
The default database that comes with the CurrentWare setup is Firebird.
For setups with more than 300 users, we recommend using SQL Server. For smaller setups, use Firebird for simplicity.
If you start off with Firebird but want to scale up to a SQL database in the future, there is a database migration tool that helps you with that.
