What is the meaning of “schema” in Oracle?

In Oracle, a Schema refers to a collection of database objects, including tables, views, indexes, stored procedures, functions, etc. A Schema is typically owned by a single user, who can access their Schema using a username and password. Schemas provide namespace management for database objects, allowing related objects to be organized together, enhancing database security and management. Additionally, Schemas can also be used to divide a database into multiple logical parts, facilitating the development and management of multiple users or applications.
