SQL License Maze

Hi, I'm not sure if this is the correct forum to ask about this, but here it goes.

I was planning to aquire the SQL Workgroup (2 processors, bla bla bla). But I realized it is not as simple as that.

Then I was looking at the different licenses and I'm not sure where I stand. The 2 processors, reporting services and

unlimited Database size is what I need. I currently use the Express Edition so I cant schedule backups within the

SQL Server and also when the database reaches 4GB will have to buy another version of SQL Server.



But which license should I have? I am a developer so all I need is an instance of the SQL Server running, nothing else.

My application will connect to it and do its job from different PCs in the netowork. I dont need any SQL Client application

running and my application uses a single user (sa) to access the SQL Server simultaniously from several PCs on the

network.



So that is why I think this is a maze to me, I don't know where to proceed. Does anyone know which license or whatever

SQL Server 2005 Workgroup version should I use?



Thanks,
