Flat File refers to a type of database where all the data is stored in a single file. Which term matches this description?

• A. Flat File
• B. Relational Database
• C. NoSQL Database
• D. In-Memory Database

Answer: (A)

Flat File is the term that matches this description: a database where all data are stored in a single file, typically a plain text file where each line is a record and fields are separated by delimiters like commas. This simple approach makes it easy to create and read data, but it lacks built-in support for tables, relationships, indexing, and complex queries that relational databases provide. Relational databases organize data across multiple tables with keys to link them; NoSQL databases store data in flexible formats such as documents or key-value pairs; In-memory databases keep data resident in RAM for fast access. So the single-file storage description best aligns with Flat File.
