However, it’s solely attainable by way of profiling, cleaning, and validation. 

Knowledge High quality, Profiling, Cleaning, Validation

Knowledge high quality has lots to do with the normalization and denormalization of a database. The previous removes redundancies and the latter integrates a number of desk information for faster queries.
