Answer 2

Data redundancy occurs when the same piece of data is stored in two or more separate places and is a common occurrence in many businesses. As more companies are moving away from siloed data to using a central repository to store information, they are finding that their database is filled with inconsistent duplicates of the same entry. Although it can be challenging to reconcile — or even benefit from — duplicate data entries, understanding how to reduce and track data redundancy efficiently can help mitigate long-term inconsistency issues for your business.
