Common checks

There can be many rules about having well organized data. Still, everything starts from cleaning the data until it does not include incorrect and inaccurate values. Removing null values, checking number of rows, identifying outliers, unmatched and negative values are some of the steps that need to be taken in order to ensure that the data is consistent and reliable. VDH provides many processors and nodes that help us perform the above-mentioned and subsequently set consistent rules and get optimized results.
