In this paper, authors have applied dominance based rough set approach on dynamic datasets. In dynamic datasets, information keeps on adding with the passage of time. So, once approximation is calculated, author proposed to update it regularly as new information is added in the dataset by considering new object as new dataset. Therefore, the computational cost of re-calculation of approximations of dominance based rough set theory when change occurs in dataset, affect the performance of the application.
