Data Cleaning helps in reducing redundancy by determining whether two or more records defined differently in database represent the same real world object. If they represent the same, then the values of the records are nested generating a new n-wMVD database. The limitation with this approach is that addition or deletion of data is not done dynamically. To overcome this limitation we propose a dynamic approach that helps in reducing the redundancy, by comparing every incoming record with

When a record to be inserted, the approach allows a decision on whether to insert or nest with the existing record. If a record needs to be updated it is verified to observe if a new
