Tableau Data Extract

Tableau data extract (.dte) -
Stores tableau data as a filtered and aggregated extract.
TDE files are data extracted from the external source such as MS Access or Excel. It is used for external data.  This data can be text,  numerical or statistical data.
TDE extracts are Tableau's method of caching data logically so as to reduce database hits for frequent access reports.
TDE extract can be refreshed manually through Tableau desktop or to be scheduled for periodic refresh through the enterprise edition.
