title: How do I fetch data from my multiple websites databases and display it in main website?
body: <p>Let's consider I have three separate websites for 3 different departments with different database, servers etc.</p>
  
  <p>And also I have a main website where I want to get some data from all three websites and show it in main website.</p>
  
  <p>E.g. In my main website if I want to get all users then it should query each of the 3 different websites, get the content and display it on my main website.</p>
  
  <p>What approach should I use to achieve this ?</p>

    <p>I am not asking for the code and queries. I only want to know the approach.</p>
