How to Improve Big Data Quality for Bigger Enterprise Insights

Authors Photo Precisely Editor | May 20, 2020

We’re dealing with more data in the enterprise than ever before. Headlines blare that “data is valuable” but, that’s only true if the information you have is of high quality. The question becomes, how do you know if your data is high quality?   

This post explores the concept of big data quality and why it is a challenge, why the enterprise needs it, and what solution you can use to ensure the quality of your data.

What is big data quality?

Data quality refers to six dimensions of information: 

  • Completeness: The information is comprehensive 
  • Consistency: Representations of an item match across all data stores
  • Unique: A piece of information is one-of-a-kind
  • Valid: Information matches the rules specified for it
  • Timeliness: Information is up-to-date and ready for use
  • Accuracy: Information is correct

Not all of these dimensions will necessarily apply to your data. For example, you might not need data to be complete, yet you always need it to be accurate and timely. 

“Big data quality,” then, refers to the data quality dimensions your big data possesses. Today, the importance of data quality in big data has risen because of big data’s prevalence.

Why is it important?

The quality of your big data matters because so many organizations use that data to make business decisions. It can come from so many sources, in so many formats, with so many rules applied to it previously, it is not always trustworthy. In fact, only 35 percent of senior executives have a high level of trust in the accuracy of their big data analytics. 

Imagine you are deciding whether to expand into a new market. You have garnered information about your potential customers, market conditions, regulations, etc. but you don’t know how old your data is. If it is out of date, you don’t know if you’re making the right decision or not. When you are sure of the quality of your data, you can trust your decisions.
