Answer
# 1
Loop is a continues path between the tables trap also is a kind of loop Due to oracle limitation some time it give multiple duplicate values when 3
tables join continuously with 1-N and 1-N and Cartesian
product also occurs. To resolve the traps and loops we should use alias, context and shortcut join. We can find the loops by checking Integrity check in Universe but can be find by view only, to resolve the fan trap better to go for alias and for chasm trap context.
