Difference between SQL Server and Oracle 'User'

Question

Are there any differences between a user in SQL Server and one in Oracle? If so, what are they?

Answer 1

In Oracle, the users and the schema are one thing. You can create two different tables with the same name, belonging to different users.

In SQL Server, schema and user are separate things. The users are only used to log in and define permissions.
