    Live Connections Vs Extracts

    Naresh MG

      Hello Folks,

       

      What exactly is the difference between Live connections and Extracts.

       

      Would it be correct or incorrect to say the following please ?

       

      Live - This is nothing but a real time EXTRACT.

       

      Extract - This is a EXTRACT which you schedule at regular frequencies.

       

      In other words in cases both there is an EXTRACT in which the data is extrcted into the tableau worksheet.

       

      So If I had a star schema with one fact table and a couple of dimensions...all the data from this is extracted in the dashboard.

      Its not a LIVE sql that is sent to the database for processing ?

       

       

      Thanks,

      Naresh
