title: Ionic project with database
body: <p>I am trying to create a mobile project , which is my first project in Ionic platform. 
  for same , I have to learn Angular and Ionic. So I decided to make a simple mobile project. 
  I have googled too much for Database in mobile technology so I got many of  database like- MongoDb, SQLite, Firebase etc. so I was the bit  confused about which database should I use in the ionic mobile project? 
  And Is there any beginners documentation for any database that  helps me to implement the database in my ionic project?</p>
