Is this an accurate way to describe the difference in the meaning of schemas between the two technologies?
- An Oracle schema is associated with a single user and consists of the objects owned by the user.
- A MS SQL Server schema is a namespace.

Oracle schemas are like My Documents folders in the Windows OS. A user can grant permissions to other users to see things in their schema but an Oracle schema is essentially a user's workspace.
MS SQL Server's schemas are namespaces. While you can have Accounting and Marketing schemas, they are not tightly-coupled to individual users. Objects in an Accounting schema contain accounting information and objects in the Marketing schema have marketing information.
Oracle schemas are tightly-coupled to users and MS SQL Server schemas are primarily for classification.
