Some Comments on Big Data and Data Science

Based on previous paper titled in “Data, DIKW, Big data and Data science” presented in ITQM2014 and published in Procedia Computer Science we will make some modifications. We discuss the relationship between data and data–information–knowledge–wisdom. Now the big data occupies much attention in some extent for his volume, velocity, and variety. But in practical use the value plays more important role. Finally to judge the value for data not necessary for big, in some cases the small data also may lead to big value. So we appreciate the data science, which may consider more inherent value from data. We will make some comments on the big data and data science from another angle.
