Flat File Database
A flat file database is a simple data storage system that stores data in a plain text file, typically using a structured format like CSV, JSON, or XML, with each line representing a record and fields separated by delimiters. It lacks the relational features of traditional databases, such as tables, joins, or complex queries, making it lightweight and easy to implement. This type of database is often used for small-scale applications, configuration files, or data interchange between systems.
Developers should learn and use flat file databases when working on projects that require minimal data storage without the overhead of a full database management system, such as small scripts, prototypes, or embedded systems. They are ideal for scenarios where data is read-heavy, simple to structure, and doesn't require transactional integrity or complex relationships, like storing user preferences, log files, or static datasets in applications like mobile apps or IoT devices.
