Like industry types, testing applications dealing with big data is very different.
One of the biggest quality challenge in the big data space is of ‘Data Quality’.
Big data mostly deals with analyzing large data sets and extracting useful information / insights from it.
The real currency here is data, therefore quality of the data you get will heavily affect the results, hence quality.
What ‘data quality’ would mean for each product & insight will be different.
So the first step is, figuring out the ‘definition of data quality’ for a particular product and the insights we are trying to get.
