Which of the following is NOT a function of databases?

Databases are primarily designed to store, manage, and retrieve data efficiently. The functions that databases commonly perform include retrieving records based on specific criteria, updating records in bulk to ensure data integrity and consistency, and performing complex aggregate calculations for analysis and reporting purposes.

The process of generating random data, however, is not a core function of a database. While some databases can facilitate the insertion of random data through specific commands or procedures, this is not an inherent functionality. Instead, generating random data is typically managed by application-level programming or specific data generation tools, rather than being a fundamental trait of database systems. Thus, stating that generating random data is a function of databases is inaccurate compared to the other options listed, which accurately represent essential database operations.
