Number of licences & Calls

My Problem is that I don’t know really what does a call means.

We got a SQL Standard Edition.

Can I install as many instances I want in a Server?

How many users can access the Server at the same time?

If I use SQL authentication, and two users use this logging information, how many calls do they made? 2 one per each user (PC) or just 1 one per logging.

If I have a client / server application, and the server access the SQL Server using SQL authentication. Can I have unlimited number of clients?

SQL Server is generally speaking licensed per processor or per Client Access Licenses (CALs). CALs, are merely the maximum number of CONCURRENT USERS you may have. Thus, if you had 10 CALs, up to 10 Clients could access your SQL Server at the same time. In my experience, most companies purchase the product on the CPU model though it is usually not cheap.

Can I install as many instances I want in a Server? Not sure license wise on this, but my hunch is yes

How many users can access the Server at the same time? See above, CPU model is unlimited clients, CALs are not unlimited.

If I use SQL authentication, and two users use this logging information, how many calls do they made? If at the same time, 2 CALs, else 1.

Hope this Helps,

Derek

Standard Edition is limited to a maximum of 16 Instances.

There is no limit to the number of users. However, each user MUST have a Client Access License (CAL) UNLESS the server is operating under a 'Processor' license.

Effective End Users count as a user, not the number of Logins, or servers accessing data, etc.

For a Public Web application, where client licenses cannot be determined, requires a 'Processor' license. A private web application may operate with each client having a CAL and the server only a 'server' license.

So, to clarify, each end user of data served by SQL Server MUST covered with a CAL or the server MUST have a 'Processor' license.
