@loop:

we can say simply like:

loop is a contineous path between
the tables.

we can say another way: if there are number of tables
extractiing with number of ralations ships connecting with
each other is called loop.

two ways to we can resolve the loop
1) Alias
2)context

if our table having only one lookup then we go for the alias
concept to resolve the loop.

if our table having more than one lookup the we go for the
context to resolve the loop

Is This Answer Correct ?
