Flat Files
Flat files are simple data storage files that store data in a plain text or binary format, typically organized in rows and columns without complex relationships or structures. They are commonly used for configuration, logging, data exchange, and small-scale data storage, with formats like CSV, JSON, XML, and plain text. Unlike relational databases, flat files lack built-in querying, indexing, or transaction support, making them lightweight but limited for complex data operations.
Developers should use flat files when dealing with simple, small datasets, configuration management, or data interchange between systems, as they are easy to create, read, and modify with minimal overhead. They are ideal for scenarios like storing application settings, exporting data for analysis, or handling temporary data in scripts, but should be avoided for large-scale, concurrent, or relational data needs where databases offer better performance and features.
