You can access and edit these files by using any text file editor, such as Notepad or vi. The file handling which we learn under C/C ++ is the example of file processing system. Use flat file databases for DSS (Decision Support Systems), Data Warehouses, Data Marts, and Operational Databases that are not accessed concurrently by multiple-users for both read/write. A CSV file is a good example of a flat file to store records as an in the case of an email list. It makes our work easier compared to writing the data on paper.
