What is DB2?

DB2 is a database server developed by IBM that provides a robust environment for managing and accessing data. It is used for storing, retrieving, and managing data in databases and supports multiple data models, including relational, XML, and JSON. DB2 is designed to handle large volumes of data, making it an essential component in enterprise-level data management systems.

As a database server, DB2 offers features such as data integrity, security, and high availability, which are crucial for applications that require reliable data storage and access. It also provides tools for database administration, query optimization, and system performance management, allowing businesses to efficiently manage their data resources.

While programming languages, data visualization tools, and operating systems serve important functions in computing, they do not fulfill the specific role that DB2 provides as a dedicated platform for database management, which is why this option correctly identifies DB2's primary purpose.
