    From Ask Tom

    You should consider a schema to be the user account and collection of
    all objects therein as a schema for all intents and purposes.

    SCOTT is a schema that includes the EMP, DEPT and BONUS tables with
    various grants, and other stuff.

    SYS is a schema that includes tons of tables, views, grants, etc etc
    etc.

    SYSTEM is a schema…..

    Technically — A schema is the set of metadata (data dictionary) used
    by the database, typically generated using DDL. A schema defines
    attributes of the database, such as tables, columns, and properties.
    A database schema is a description of the data in a database.
