Can a database have different schemas?
Here, a database can have multiple schemas (or “schemata,” if you’re feeling fancy). Each one contains all the objects created by a specific database user. Those objects may include tables, views, synonyms, and more. Some objects cannot be included in a schema, such as users, contexts, roles, and directory objects.
Should you use DBO schema?
dbo is the default schema in SQL Server. You can create your own schemas to allow you to better manage your object namespace. As a best practice, I always add the “dbo.” prefix even though it is not necessary. Most of the time in SQL it’s good to be explicit.

A schema is now an independent entity- a container of objects distinct from the user who created those objects. Previously, the terms ‘user’ and ‘database object owner’ meant one and the same thing, but now the two are separate.
How to query a table without specifying DBO schema?
In the table properties it lists ‘erpadmin’ as the db schema. When I write a query I now have to include ‘erpadmin.’ in front of all the table names which is confusing. If you want to go back to using the dbo schema like you were in SQL Server 2000, you can move the table back into the dbo schema:
Can a DBO be the default schema owner?
When the users TestUser1 and TestUser2 create objects, the objects would be created in their default schema (Development Schema). Just wonderiing if I am headed in the right direction and should the goal be to have ‘dbo’ own the schemas but allow database users to create objects within the schemas.
