Join Type

Normal Join A normal join will allow only those records which satisfy the joiner condition for both sources. So remaining records, who don’t match the condition get discarded Master Outer Join A master outer join will keeps all rows of data from the detail source and the matching rows from the master source. If any of master records don’t satisfy the condition , those rows get discarded. Detail Outer Join Just opposite to Master Outer join , it keep all rows of data from Master Source and the matching rows from Details Source. If  any of detail records don’t satisfy the condition , those rows get discarded. Full Outer Join A full outer join keeps all rows of data from both the master and detail sources.
