Following are the problems that are solved by Datapools :

1. To provide data to the application which accept only unique data in each iteration to avoid already exist error ie. application that receives unique data only as input.

2. To provide data to the applications which deletes data from the database. If data is same and it is deleted in first iteration then it will give no data found error in subsequent iterations.

3. To provide unique data in performance testing so that application performance can be evaluated as per real time scenario.
