2. The practice of implementing measures and protocols to protect the database system from unauthorized access, data breaches, and other security threats.
3. Ensuring that the execution of multiple transactions produces the same result as if they were executed sequentially.
4. A request for data or information from a database.
5. A file that records all the transactions and activities in a database system.
6. The structure that defines the organization of data, including the tables, fields, and relationships within a database.
