AX 2012: Forms and Tables methods call sequence

Many a times we came across the point that where should we write code either it would be in init() of a form or in datasource init() method. And which method will be called first and where you can actually retireve record and what would be best way to accomplish few basic requirements without impacting the performance.

For all above reasons I found an interesting link and thought it would be worth sharing here.
