I am new to schema, roles and user management part in sql server. Till now I used to work with simple dbo schema but now after reading few articles I am intrested in creating schema for managing my tables in a folder fashion.

At present, I want to create a schema where i want to keep my tables that have same kind of functionality. When I tries to create a schema then I faces a problem while using query, permissions etc.

First of all i want to get used to of using schemas then only I want to explore it. But due to initial stages and work pressure as well i m not able to implement it yet.

What can i do to start using schema with default permissions as that of dbo. Also let me know about creating roles and assigning roles on these schema. I want all this to be accessible by sa user itself at present.

What is the concept behind all these things
