1.Data completeness test are designed to verify that all the
expected data loads into the DWH.

that all records,all fields and full contents of each field are loaded correctly or not.
3.Strategies to consider includes:

data.
b)Comparing record counts between source and data loaded to
the warehouse (Target) and also rejected records in warehouse (Target).
c)Comparing unique values of key fields between source data
and data loaded to the warehouse (Target) column mapping from the source or stage.
