Question

mismatched redundant copies of data is known as data ____​

Answer 1

Answer:

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.

Redundancy is definitively a copy, but the access to either version of the data is 1 to 1 exactly the same to you. The RDBM may choose one or the other based on different parameters such as how fast or whether the other computer network connection is down.17 06 2014

The main difference between data redundancy and data inconsistency is that data redundancy is a condition that occurs when the same piece of data exists in multiple places in the database whereas data inconsistency is a condition that occurs when the same data exists in different formats in multiple tables.
