Techopedia Explains Data Redundancy
Within the general definition of data redundancy, there are different classifications based on what is considered appropriate in database management, and what is considered excessive or wasteful. Wasteful data redundancy generally occurs when a given piece of data does not need to be repeated but ends up being duplicated due to inefficient coding or process complexity.
