SQL Server 2005 Licensing Concern.

Hello,

Our company has developed several Access applications for our clients
and we wish to expand to use a database server. We wish to use Access
as the front end application and SQL Server 2005 as the back end
Databes Server. Making a Server-Client application database.

I'm very new to SQL Server so my concern is how the licensing works
for a developer like us. I am aware that we can purchase the Developer
edition for $49 USD. Our clients will then have to purchase a their
respective licensing option.

We do not have an issue with this, but i would like a better
understanding of how this works.

1) The developer edition (DE) is the same as the Enterprise edition.
Would our clients have to buy the Enterprise edition ($24,999) if we
develop the SQL server in the DE? Or can they purchase the Standard
or Workgroup edition if the workload allows it?

2) If the client already has the Enterprise Edition on the Server we
wish to use, will they have to buy the license again if we create the
Database? Can they import our Database to thier SQL Server, and our
application connects to thiers?

3) Is there other options that would require a cheaper option for our
clients?

4) With just the DE, can we develope applications and use the
appropriate edition for our clients whatever it is?

5) To test our products we thought of using the Trial version to
simulate a multi-user test environment? Since thats just a 180 day
trial, perhaps the Worgroup Edition or the Light weight Edition might
work. But these editions might not be compatible with our clients'
requirements. The DE doesn't seem to handle multi-user environments,
so we cant effectively test how the application will perform in the
"real world". Any advices here?

Our clients range from small bussiness to nation-wide to multi-
national companies.

Thanks,

- GL
