Question

Quizplus · Accepted Answer

A database schema is a visual representation of the database that shows its organization, structure, and relationship among its tables, attributes, and keys. It provides a blueprint for the database design and serves as a reference for developers and users to understand how the data is stored, retrieved, and manipulated. A data graph is not a commonly used term for describing a database model. A shadow schema refers to a copy of a production database that is used for testing or development purposes. A referential schema is a type of database schema that describes the referential integrity constraints among the tables in a database.
