What is a flat file database?

A flat file database is correctly defined as a database that consists of just one table. This structure is caracterized by its simplicity and ease of use, as all the data is stored in a single, often tabular format, where each row represents a single record, and each column represents a data attribute. This format makes it straightforward to manage and access data, especially for smaller datasets or applications that do not require complex relationships between different types of data.

In contrast, a database with multiple interconnected tables involves more complexity, typically seen in relational databases. While flat file databases are effective for certain use cases, such as storing simple lists or logs, they lack the ability to efficiently handle complex queries that involve relationships between diverse datasets. This distinction is crucial when determining the appropriate database structure for different data management needs.
