What is diff b/w Alias and Contexts in which situation we are using contexts instead of Alias?..

Answer / sonia

Contexts and Aliases are means to resolve loops/traps in
universe designs. Contexts are used to specify which of the
paths should be used when more than one path is possible
from one table to another in a loop. Contexts are used in
the scenarios where two or more many-to-one joins converge
on a single table. Whereas Aliases are used to resolve the
loops by duplicating the table and defining separate paths
when one-to-many join links to a table which is again
linked to another one-to-many join.

Answer / saichand

The main diffrence between them is if the loop is formed
between 1 fact table and 2(0r) more dimensions tables,then
create an alias for existing dimension tables.if loop
constitute more than one fact table then in this case go
for contexting.
