Databases need to attain all the ACID elements (atomicity, consistency, isolation, durability) and, if you're going to ensure that's all done in a flat file (especially with concurrent access), you've basically written a full-blown DBMS.

A flat file database contains information that, as often as possible, is stored in the order in which it is needed. It contains flat files that have no relation to other files (when only one table is stored in single file, then this file is known as flat file). Accessibility of data: You can store data in a database by using a very complex data structure, specifying data types and relationships among the data. A flat file system usually stores the same type of information over and over again, whereas a relational database does not. The approach of a flat file database is contrary to the approach of a relational database, in which how information is stored does not matter; how it is retrieved does. let me know from your experience.
