User vs. schema in Oracle

An Oracle user asks what the difference is between a user and a schema.

What is the difference between a user and a schema?
Technically, a schema is a collection of database objects owned by a specific user. Those objects include tables, indexes, views, stored procedures, etc. In Oracle, a schema requires a user to be created. But you can create a user that has no schema (i.e, no objects). So in Oracle, the user is the account and the schema is the objects. It is possible in other database platforms to have a schema without a user.
