Hi
To my humble understanding, and please correct me if I am wrong, Mondrian
uses full outer joins to join dimension tables with fact tables in a
snowflake schema, and uses right outer joins to join dimension tables with
fact tables in a star schema.
I am not sure if my understanding is completely right and I will appreciate
an assertion.
If my understanding is completely right, then Mondrian will not require
full outer joins if a star schema is always enforced, and will never
require left outer joins.
Any feedback is appreciated. Thanks.
