title: Scheduled tasks concept
body: <p>I am new to the scheduling.</p>
  
  <p>I created a website with two buttons. <br>
  One for import data from text file to database.<br>
  Another one for joining data in excel and database.</p>
  
  <p>Now what I want to do is
  as every week, a new text file will be uploaded, I want to schedule so that my application import data to database every week.</p>
  
  <p>How do I do it? I just need the concept.
  What I think now is to schedule the server to make web request every week. Is this correct? Is there other better ways?</p>
