Understanding the Pillars of Data Quality

Imagine, you are baking a cake. You have all the ingredients except eggs. Of course, you could improvise but most probably instead of the moist chocolate cake, you end up with a dry science experiment. Incomplete data leaves everyone unsatisfied.

During the decision-making party, every data quality dimension is an important guest with a unique vibe:

Good Data should be Complete, when all data attributes, that describe data in its fullness, are present as a part of your data. This guest keeps the party snacks stock full and makes sure no one gets hungry. Incomplete data leads to half-baked insights.

Good Data should be Accurate. This means that the data correctly describes its objects and accurately reflects the reality. This party guest is a perfectionist, checking that the playlist is perfectly chosen.

Good Data should be Timely. This means that the data is fresh. No one wants to eat last week's sushi. It's not only unappetizing; it is downright risky. This guest makes sure everyone at the party shows up on time - no fashionably late nonsense.

Good Data should be Consistent. This means that data in the different datasets is the same. Having inconsistent data chaos is like measuring weight in kilograms and pounds interchangeably. This party guest makes sure that everyone sticks to a dress code - no pyjama rebels allowed. 

Good Data should be Relevant. This means that the data is useful for the specific use case. Imagine making spaghetti but reading a pancake recipe. Irrelevant data makes noise, not providing any value to your analysis.

Good Data should be Valid. Validity is about following the rules. This means that data conforms to the required format and standards, and fits within defined rules and constraints. The invalid data format is like pouring orange juice into your soup.

Good Data should be Unique, ensure no duplicates exist and that every record is one-of-a-kind. It's like two guests at the party saying exactly the same thing, which is pointless and annoying.

Data Party, where guests don't vibe together will lead to incorrect conclusions and bad strategic choices.
