I am in the process of establishing a "sandbox" database for a mix of users with SQL development skills. I have done this before with Oracle but not with SQL Server. What I would like to do is build a database whereby each user has their own play area. We are running SQL Server 2005 so I thought of using Schemas to do this. My plan is to create a schema named for each user and to make that user the owner. Because I am still not knowledgeable of SQL Server permissions, I am curious as to how to establish an environment whereby each user has total control of their schema and can grant or revoke privileges to their objects at the schema level or a more granular level. Is this possible? Have you any suggestions as to best practices for establishing the environment I am trying to construct?
