title: SQlite Database VS Room persistence library
body: <p>I need help for my exam project to find differences and benefit of ROOM database: 
  I tried to search in android development documentation to understand the difference between these two databases, but i couldn't clearly understand. 
  I did not find any answer in stack overflow either. 
  I also want to know the benefit of using Room persistence compared to SQLite database. </p>
  
  <p>Hope someone can give me clear answer. </p>
