FLAT FILE VS DATABASE MODEL

The problems with flat files that are resolved by Database technology include:

Data Storage --- Flat files result in considerable data redundancy and storage problems

Data Updating -- 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.

Currency of Information -- If update information is not properly disseminated, the change will not be reflected in some users’ data, resulting in decisions based on outdated information.

Task-Data Dependency -- The user’s information set is constrained by the data that he or she possesses and controls

Flat Files Limit Data Integration -- The flat-file approach is a single-view model. Files are structured, formatted, and arranged to suit the specific needs of the owner or primary user of the data.
