What's the difference between the YouWinLaw Editions?

YouWinLaw Personal and Workgroup Editions use Microsoft Access (mdb) for their database (Access must not already be installed. We do not use any runtime modules from Access). The Personal Edition is for one user, the Workgroup Edition for up to 5 users in a network.

On the other hand, YouWinLaw Professional and Enterprise Editions use a Microsoft SQL Server for their database server.
YouWinLaw Professional edition use a free Microsoft SQL-Server Express for the database server.
YouWinLaw Enterprise Edition use a Microsoft SQL-Server for their database server. YouWinLaw is then a full client/server application, running at optimized speed and reduced network traffic (and delegating most of the work to the SQL Server).
