Difference Between Flat File & Relational Database. A flat file database stores data in a single table structure. A relational database uses multiple table structures, cross-referencing records between tables. Tables in both organize records in rows, with each column containing a single piece of data in the record.

SQL databases are table based databases whereas NoSQL databases can be document based, key-value pairs, graph databases. SQL databases are vertically scalable while NoSQL databases are horizontally scalable. SQL databases have a predefined schema whereas NoSQL databases use dynamic schema for unstructured data.
