Data profiling is process of exploring the data available in order to get some idea about it. We can perform several tasks in this step like,
- Find number of missing values from each column (count)
- Find null values from each column (these are not missing value)
- Find count of useful values from each column (not-Null and not-missing)
- Find percentage of useful values from each column
- Find cardinality of each column (number unique values)
- Find distinctness as percent calculated by dividing cardinality with actual value count
