How to Improve Big Data Quality for Bigger Enterprise Insights

Enterprise 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 got is of high quality. The question becomes, how do you know if you have high-quality data? 


This post explores the concept of big data quality and why it is a challenge, why the enterprise needs big data quality, and what solution you can use to ensure the quality of big 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 big data quality has risen because of big data’s prevalence.

Why Is Big Data Quality Important?

Big data quality matters because so many organizations use big data to make 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 If it is out of date, you don’t know if you’re making the right decision or not.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 your big data quality, you can trust your decisions.
