inconsistent data

Explanation:

Data inconsistency refers to a situation where similar data is stored in more than one file but with different formats. This may lead to data duplication and can compromise the integrity of the information.

For example, when you register a user's name and address or telephone number, and different data is matched with the same customer name. So if you search for the customer's information, you will receive inconsistent data since the old address or telephone number will also show up and they do not match the new one.

When this happens, companies must match the data between files by purging obsolete or mistaken data.
