Explain the similarity and difference between the data update and information currency problems associated with flat files. 

Solutions

Expert Solution

The data update problem in a flat-file model occurs because organizations have a great deal of data stored in files that require periodic updating to reflect changes. For example, a change to a customer’s name or address must be reflected in the appropriate master files. When users keep separate files, all changes must be made separately for each user. This adds significantly to the task and the cost of data management.

Information currency problems occur because user failing to update all the user files affected by a change in status. If update information is not properly disseminated, the change will not be reflected in some users’ data, resulting in decisions based on outdated information.
