Circular dependency scenario

Hi Experts,

I want scenario with circular dependecies.

For eg we have two fields

• emp name and
• emp manager.

We entered emp manager and we get list of employees under him.

Now from the list we got may be some employees are manager of others.

So next the info about that EMP as manager will come.

Can anyone help me in that....

Ant database table for this retreival?

Thanks,

Akriti
