title: Which is better separating big data into 2 tables or collect it all in one
body: <p>I am creating a web app that has a big load of data for its items. I was wondering if separating the data into 2 tables (ItemData &amp; ItemDataDetails) would decrease the execution time of the queries. 
  My drive is that I have 2 pages, 1 page which displays the most basic info regarding the item and another that shows the details. By logic I think that it should decrease the load time for the page where the basic info is showed. Am I correct or not?</p>
