2) Conceptual

4) Physical

Answer 1

The database schema is part of the Conceptual layer of the ANSI/SPARC model, which abstractly defines the database without considering the technical details of storage or operation.

Step-by-step explanation:

The database schema is contained in the Conceptual layer of the ANSI/SPARC model.

This model comprises three layers: the External layer, which is the users' view of the database, the Conceptual layer, where the database schema is defined abstractly without any hardware or software considerations, and the Internal layer, which describes how the data is actually stored in the database.

The Conceptual layer represents the entire database as a whole from a conceptual point of view without delving into the low-level technical details of how the data is stored or how the database should operate.The database schema is contained in the conceptual layer of the ANSI/SPARC model.
