Flat File data format (FF/EDM) – FF/EDM is a spreadsheet-compatible, comma separated values (CSV) file format whose content is specified by NAESB standards. All the rows in the flat file database follow the tuple concept in relational algebra, where tuples are an ordered list of elements. CSV files are files where table data is gathered in lines of American Standard Code for Information Interchange (ASCII) text with the value of each table cell separated by a comma, with each row represented by a new line. While it uses a simple structure, a flat file database cannot contain multiple tables like a relational database can. Simple systems can easily contain basic information for a quick database.
