Please Elaborate On The Difference Between TMap And TJoin In Talend.

tMap does the job where it can accept only two input links which are primary and lookup, and it can have multiple output links, it can also filter data using filter expressions. On the other hand, tJoin accepts various input links in which one is main, and the others are lookups, unlike tMap it has only two output links, and it cant filter using tJoin command.
