When u are creating master detail relationship , the master is required, just like in real situation ,
if there is a employee,it must work for a company(tight bound), if company closes then there will be no employee, if parent is deleted, child automatically deleted too.
And in lookUp ,there is no need of parent, if parent is deleted, no effect on child.
Hope this helps.
