Question

• A. Data redundancy
• B. Information overload
• C. Duplicate data
• D. Data inconsistency
• E. None of these

Answer 1

The correct option is D Data inconsistency

When data changes in multiple lists and all lists are not updated, this causes Data inconsistency.

Data inconsistency occur between files when similar data is kept in different formats in two different files, or when matching of data must be done between files. As a result of the data inconsistency, these files duplicate some data compromising data integrity.

Data redundancy and inconsistency: Data redundancy means duplication of data and inconsistency means that the duplicated values are different. Integrity problems: Data integrity means that the data values in the data base should be accurate in the sense that the value must satisfy some rules.
