  • B. No
Show Suggested Answer Hide Answer
Suggested Answer: A 🗳️
Use a matching rule, and use completeness and uniqueness data to determine what weight to give a field in the matching process.
If there is a high level of uniqueness in a field, using the field in a matching policy can decrease the matching results, so you may want to set the weight for that field to a relatively small value. If you have a low level of uniqueness for a column, but low completeness, you may not want to include a domain for that column.

Answer ist yes? I dont think so .Why should the adaption of the weight help to review the completeness and uniqueness. In my opinion: this is no since we need to profile the data by means of the profiler which can be started after creating a matching rule
