Data errors occur in various ways when data is transferred from one point to the other. These data errors occur not necessarily from the formation/insertion of data but are developed and transformed when transferred from one process to another along the information chain within the data warehouse infrastructure. The main focus for this paper is to conceptualize the data cleansing process from data acquisition to data maintenance. Data Cleansing is an activity involving a process of detecting and correcting the errors and inconsistencies in data warehouse.
