Similar to searching through flat files, any relationships and validation between different flat files would have to be programmed and likely be of limited capability.A flat-file database structure refers to the virtual storage method of an information set in one of its simplest forms. For a file system database, data can be stored in individual files or multiple files. The advantage of the various database models is that they provide some of this programming for you. Werbung Any searching through flat files for data has to be explicitly programmed. In this respect, a comma-delimited CSV file used with Excel is not a flat file.

Using a file system database model implies that no modeling techniques are applied and that the database is stored in flat files in a file system, utilizing the structure of the operating system alone.
