Example:



1. Flat Database - ** is ** standalone database, uses one table. The flat file design puts all database information in one table, or list, with fields to represent all parameters. A flat file may contain many fields, often, with duplicate data that are prone to data corruption and redundancy. Merging data between two flat files, create the need to copy and paste relevant information from one file to the other. There is no automation between flat files. Changing information in one file has no bearing on other files. Flat files offer the functionality to store information, manipulate fields, print or display formatted information and exchange information with others.
