How to get task hierarchy from Reporting Database ?

Hi All,

I want to retrieve complete hierarchy of task from project server reporting database.

Example is :

 Parent Task

    ----  Child Task

              ------- Sub Child 1 Task

              ------- Sub Child 2 Task

Now I want to display them like Parent Task -> Child Task -> Sub Child 1 Task. Kindly let me know from which tables / views I can get this information ?

Regards,

Mehar
