Sample Answer
Let’s define these database-related terms and then address your questions.
Definitions:
- Data: Raw, unorganized facts or figures that have no inherent meaning until they are processed and interpreted. Think of it as the building blocks of information. (Source: Adapted from “Database Systems: A Practical Approach to Design, Implementation, and Management” by Connolly and Begg)
- Database: An organized collection of structured data, stored electronically, that can be easily accessed, managed, and updated. It’s more than just a collection of files; it’s a system for managing information. (Source: Adapted from “Database Systems: The Complete Book” by Garcia-Molina, Ullman, and Widom)
