Flat Files
Flat files (also known as user-defined formats) are text files that are usually stored on the workstation or server. Flat files do not have relationships defined for them and typically use the Unicode character set. Data in a flat file usually is stored as one continuous string of information. You can use flat files to import or export data from applications that have no other means of interaction. For example, you might want to share information between JD Edwards EnterpriseOne and another system.
