Flat-file database

A flat-file database is a type of database that stores data in a single file. This means that all the data related to a particular topic is contained in one document, rather than it being spread out over multiple files. This type of database is easier to create and manage than other types of databases, as it doesn't require a lot of complicated setup. It is also more secure than other types since it's all stored in one place. However, flat-file databases are usually limited in terms of how much data they can store and they are less likely to be updated regularly.
