Which type of database centralizes all data in a single system?

• A. Federated database
• B. Distributed database
• C. Centralized database
• D. Blockchain database

Answer: (C)

A centralized database is characterized by the consolidation of all its data into a single system or location. This setup allows for easier management, maintenance, and security of the data since there are fewer nodes involved in the storage and retrieval processes. Centralized databases support structured query language (SQL) and enable users to access and manipulate data efficiently from one central point. In contrast to a centralized database, a federated database system integrates multiple, distinct database systems into a unified framework but does not centralize data in one location. A distributed database stores data across multiple networked locations, which can increase redundancy and reliability but complicates data management. A blockchain database, while decentralized and secure, is fundamentally different from a centralized approach as it distributes data across a network of nodes to ensure tamper-proof recordkeeping. Thus, the concept of centralization in a database aligns perfectly with the features of a centralized database, making it the correct choice.
