Three-schema architecture is part of the Entity-Relationship Data Model. True False
Question
Three-schema architecture is part of the Entity-Relationship Data Model.
True
False
Solution
The statement is False.
The three-schema architecture is not specifically part of the Entity-Relationship (ER) Data Model; rather, it is a framework for database systems that provides a way to describe the structure of data at three different levels: the internal schema, the conceptual schema, and the external schema. The ER Data Model, on the other hand, is a conceptual tool primarily used for data modeling, which focuses on representing the data entities, their attributes, and the relationships between them. While both concepts are related to database management, they serve different purposes and are not inherently linked in the way the statement suggests.
