How to make a link between parts in Solidworks?

How can I make a link between 2 parts in solidWorks?

And second...How can I make a one way link between 2 parts?

For example...I have made 2 parts named "part01" and "part02"
I want these 2 parts have such a one way link that when I make changes on "part02" nothing changes on "part01" but when I make changes on "part01" those changes apply on "part02" too.

Please help me....It is urgent!!

I asked this question in Solidworks own forum...and I got my answer there...I think it is close to Fahad's answer...but with more details I guess!
