Which framework serves as a database map for an application and can be built from code or the database?

• A. ERD
• B. Flat File
• C. Entity Framework
• D. Encryption

Answer: (C)

This item tests understanding of a framework that maps between application objects and database structures. Entity Framework is an ORM that serves this role. It lets you work with data as .NET objects, while it handles the underlying database mappings—tables, columns, keys, and relationships. Entity Framework can be used in two common ways: code-first, where you define your domain classes and EF generates the database schema, and database-first, where an existing database is used to generate the code model. This dual capability means it can be built from code or from the database, making it the right choice for mapping the application to the database. The other options don’t fit this role. An ERD is a design diagram used to plan the data model, not a runtime framework. A flat file is a simple text-based storage format, not a mapping framework. Encryption is a security feature, unrelated to mapping data between application code and a database.
