File with a .DATA extension contains DATA in a simple text format, separated with a tab, with a specific file headline. DATA files are specific to the Analysis Studio software and along with STP files that contain their structure, information on scheme and objects, they are a complete set of DATA obtained from different sources.

Analysis Studio statistic DATA analysis and browsing software usually utilises the DATA files offline, when there is no connection with the server, for instance while obtaining DATA from MS Access databases or an SQL Server. Deletion of the headline from the text of a file enables the DATA to be easily imported to Microsoft Excel.
