Have you wondered how to manage data quality and asked the question what is data profiling? Here we talk about data profiling, and the different steps you can take to manage it, which will allow you to understand what is data profiling and how it improves your data.

So what are the benefits of data profiling?
(A) Completeness – Does the data available represent a complete picture of the data that should be present?
(B) Conformity – Is the data conforming to the correct structure as would be expected when you observe it?
(C) Consistency – If you have the same data in two different systems, are they the same values.
(D) Accuracy – There will be a need to ensure that the data present is accurate. This could fundamentally make any decisions made on the back of it not correct, which could have known on effects.
(E) Uniqueness – If there are properties of data that are unique, does the data set show that.
