Flat file databases are most often used in a “transactional” nature and when entire file processing is required, where Relational Databases are generally found in data warehousing implementations where direct record access is essential. Other examples: readings of temperatures, speed at impact, velocities. A flat file may contain fields which duplicate the data as there is no automation in flat files. A good example of a flat file is a single, text-only file that contains all the data needed for a program. If you enjoy reading this article please make sure to share it with your friends. Relational database management systems (RDBMSs) provide a number of significant advantages over flat file systems (e.g., Excel). Due to backup and recovery options databases can survive in crashes without corrupting the data. flat file: A flat file contains records that have no structured interrelationship. Alternatively called a flat database or text database, a flat file is a data file that does not contain links to other files or is a non-relational database. let me know from your experience.

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. Operating system files lack a few things that each rendition of any application shall have to address: 1. You can google "RDBMSs vs Flat Files" to see a long list of such sites. Take a Word document, for instance. There are many, many web sites that discuss the differences, and the advantages of one and the disadvantages of the other.

A database is a collection of data, which is organized into files called tables. Relational databases have the muscle to handle multitudes of data and complex queries. What’s more relational databases have trouble clustering, and scaling horizontally. A flat file database contains only one two-dimensional table of data. Databases are designed to in a way to refer to information without actually requiring to load all of the information into memory. Database system provide data consistency whereas flat file can not provide data consistency.
