what is bridge tables in informatica

Answer Posted / gangam rajesh

Bridge table is a association table between two multivalued
dimension tables i.e. which have many to many relation.
Actually database doesn't support m to m relationship so
by using this bridge table we convert the m to m relation
ship into two 1 to many relationships.Bridge table contains
primarykeys of both dimensional tables as a compositekey
