A file or series of files that store information and allow people to develop queries and reports based on the information.

• A. Cookie
• B. Database
• C. DDL
• D. CSRF

Answer: (B)

A database is a structured collection of data stored in files and managed by a database system, designed so you can run queries to retrieve specific information and generate reports from the data. This description fits because it emphasizes storage in files and the ability to develop queries and reports from that data. A cookie, by contrast, is a small piece of data stored on a user’s browser for session or preference tracking, not meant for querying across a dataset. DDL refers to the part of SQL used to define or modify the schema (like creating or altering tables), which is about structure rather than the data itself. CSRF is a security vulnerability in web applications, not a data storage or reporting mechanism.
