Sure. Data cleaning – The data you have collected may have irrelevant and missing data. Hence it becomes a necessity to clean such data. Data cleaning process includes handling of missing data and noisy data. Data transformation – This process is nothing but a process of transforming data into an appropriate form. This steps includes, normalisation, attribute selection, and discretisation. Data reduction – This is done to reduce data storage and increase the storage efficiency.
