Final answer:
The external-level schema is an individual user's view of the database and provides a simplified view that meets their specific requirements.
Step-by-step explanation:
The External-level schema is an individual user's view of the database. It represents the portion of the database that is relevant to a specific user or application. This schema defines how the data is organized and presented to the user, providing a simplified view that meets their specific requirements.
For example, in a word processing application, the external-level schema might include tables and fields for formatting options, document content, and user preferences. This schema shields the user from the complexities of the underlying database structure.
The external-level schema is one of the three levels of database abstraction, along with the conceptual-level schema and the internal-level schema. The conceptual-level schema represents the overall structure and organization of the entire database, while the internal-level schema defines how the data is physically stored and accessed by the system.
