$user_source = $this->src('user_source')->query("select id,name from users");
$purchase_source = $this->src('purchase_source')->query("select user_id,item,amount from purchases");
$join = new Join($user_source,$purchase_source,array("id"=>"user_id"));

Hi Ankit,

You apply the same concept to join the third table.

$user_source = $this->src('user_source')->query("select id,name from users");
$purchase_source = $this->src('purchase_source')->query("select user_id,item,amount from purchases");
$join = new Join($user_source,$purchase_source,array("id"=>"user_id"));
$together = new Join($join,$another_source,array("id"=>"user_id"));
$together->pipe($this->dataStore('together'));

Hope that helps.
