Correct Answer :
B. Operational database
The database which is used to manage and store data in real time is called Operational database. An operational database management system is software that is designed to allow users to easily define, modify, retrieve, and manage data in real-time. While conventional databases rely on batch processing, operational database systems are oriented toward real-time, transactional operations. Operational databases, which can be based on NoSQL, are the source for data warehouses and are critical to business analytics operations.
