Cartesian product is getting incorrect results.
for instance if we have a cham trap or a fan trap n we din't solve them after checking the integrity also we get duplicate results of the same record ie nothing but cartesian product.
ex:-
we have customer,orders,loans classes
orders for one product if the product_price is 150$ it will appear twice in the report due to traps bcoz of the cartesian product thats why to solve the cham trap we create context and in order to solve fan trap we create alias table.
3. Explain the difference between union and group?
The difference between union and group is as follows:
take two tables t1 and t2.

so union means t1 union t2 i.e getting result from both tables i.e a,b,c,d,e.,f
where as group performs on a individual column in a particular table.
to get good name , fame n earn well amt is top business.
We can do this in three ways
1.alphabetical order-prompts will appear in alphabetical order
2.numeric order-prefix number and they will appear in numeric order
3.date order-prompts will appear date wise
it depends on the type we choose in prompt syntax
