Which two of the following operations are NOT part of data cleansing Database schema creation with appropriate data types matching the ingested data. Replacing of 'n/a' column entries with NULL values. Detecting and correcting inaccurate data, such as matching cities to correct postcodes. Harmonisation of data, such as converting string-representations of numerical data (eg. 'one') to equivalent numbers (eg. 1). Detecting and removal of incomplete data entries. Data anonymisation for privacy protection, eg. by removing personal names. Transformation of data from different sources to the same units of measure (eg. uniformly using days for the values of a duration). Outlier removal.
