Data Cleansing - Also referred to as data scrubbing. Data Cleansing is the process of detecting dirty data in a database (data that is incorrect, out-of-date, redundant, incomplete, or formatted incorrectly) and then removing and/or correcting the data. Data cleansing is often necessary to bring consistency to different sets of data that have been merged from separate databases. Cleansing data involves consolidating data within a database by removing inconsistent data, removing duplicates and reindexing existing data in order to achieve the most accurate and concise database. It can involve manual tasks or processes automated by special Data Quality tools. A particular type of Data Cleansing is Address Cleansing, in which street addresses are converted to a standard format as set forth by the U.S. Postal Service master database. For example, standard abbreviations are utilized, typos are corrected and ZIP codes are converted to 9-digit format. Address cleansing is usually done in conjunction with address matching, a process that validates an address against one of the 57 million addresses in the USPS database.

Data Cleansing - The process of manipulating the data extracted from operational systems so as to make it usable by the data warehouse. When loading data from existing operational systems, it is likely that few if any of the operational systems will have data to present in a format which is compatible with the data model developed for the Warehouse. For example, a product number may be held as a numeric field in one system while a second system appends an alpha suffix to the number for reporting purposes.
