The most important asset for today’s economy is data. A lot of businesses, organizations and governments deeply analyze their data, from sales to health, in order to gain useful insights that can be exploited to improve services or products. Indeed, we are in the so-called data-driven economy. Lots of decisions are affected by data and many automated systems don’t need any human supervision at all. As a result, having bad quality data will result in failures or unattended results in most cases. For this reason, having good data that is reliable is becoming a priority for many industries and public sectors.
