The need to clean data for effective insight
There is more data today than ever before. In fact, the total amount of data created, captured, copied, and consumed globally has now reached an incredible 149 zettabytes. The growth of the big mountain is not expected to slow down, either, with it expected to reach almost 400 zettabytes within the next three years.
Whilst more data generally leads to more insight, the quality of that insight can only be as good as the quality and relevance of the data going in. Ensuring that the right data is collected − not just in terms of volume but in context and accuracy too − is paramount. Once this bad data infiltrates the system, problems begin. Yet, keeping data clean and true can be a real challenge.
