An error data,duplicate data and data inconsistency is a big problem In a Database system. Many researcher's are trying to implement and solving a specific model for data cleaning and that will help to keep quality data in the data warehouse. Data quality is a critical factor for Data Warehouse and Data Integration System. Improving the quality of data is important because it is used in the process of decision support, which requires accurate data. Data cleaning is the process of the identifying and removing or correcting error in the data. Data cleaning is a key precondition for analysis deci...
