Which system is designed for defining, creating, manipulating, controlling, managing and using databases?

• A. DBMS
• B. computer architecture
• C. digital data
• D. graphics tablet

Answer: (A)

A database management system is designed to define, create, manipulate, control, manage and use databases. It provides the tools to design the database schema (how data is organized), actually create the database, and perform operations such as inserting, updating, deleting, and querying data. It also handles access control, enforces data integrity, coordinates concurrent access with transactions, and manages backup and recovery. In short, it’s the centralized software that enables storing data and interacting with it in a controlled, reliable way. The other options relate to hardware design (computer architecture), basic data form (digital data), or a peripheral input device (graphics tablet), none of which cover the full set of database-related capabilities.
