ELT makes the arduous task of coding large amounts of data by hand unnecessary, reducing both the time spent on it and the need to pay someone to do it. ELT also helps make the data easier to understand. By compiling it into a central model, ELT makes large chunks of data more digestible and presents them in a manner that is easier to "read" by humans. Finally, ELT keeps the memory demand on the servers of businesses light.
