Jan 24, 2023 · Flat files use a flat data model, which is a simple data model that stores data in a single table with no relationships. Relational databases provide a variety of data access methods, including SQL, which allows for complex queries and data manipulation. Flat files can only be accessed and manipulated through simple file I/O operations.

Linear stores of NoSQL data, JSON data, primitive spreadsheets (perhaps comma-separated or tab-delimited), and text files can all be seen as flat-file databases because they lack integrated indexes, built-in references between data elements, and complex data types.

Flat model. The flat model is the earliest, simplest data model. It simply lists all the data in a single table, consisting of columns and rows.
