What is Schema in SQL?

Answer 1

In a SQL database, a Schema is a collection of various logical data structures. The database user owns the schema and it has the same name as that of the user. It is considered as an independent entity or in simple words, a container of objects. It is similar to containers or namespaces that can be used to store database objects.

The main aim of Schema in SQL is to aid in security management. It helps in defining which users have the authority to access which database objects. Some of the major characteristics of SQL Schema includes:

• The ownership of the schema is transferable
• You can move the database objects among the schemas
• You can share a schema among many users
• The user can easily be dropped without affecting the database object that is associated with that user
