When you need to change data, redundancy also makes your changes more cumbersome and time-consuming. Even if you use the global find-and-replace feature, multiple changes require more computer time than does a single change. Finally, redundandy can lead to inconsistencies. For example, you might enter the same name in the same column, and then not be sure which is the correct spelling. Further, if that names spelled in three different ways and you use the search feature with one of the three values, you'd find a single match instead of three matches.
