Popis: The focus of data science is data analysis. This article begins with a categorization of the data science technical areas that play a direct role in data analysis. Next, big data are addressed, which create computational challenges due to the data size, as does the computational complexity of many analytic methods. Divide and recombine (DR deep analysis of the data, which means analysis of the detailed data at their finest granularity; easy programming of analyses; and high computational performance. To succeed, D&R requires research in all of the technical areas of data science. Network cybersecurity and climate science are two subject-matter areas with big, complex data benefiting from D&R. We illustrate this by discussing two datasets, one from each area. The first is the measurements of 13 variables for each of 10,615,054,608 queries to the Spamhaus IP address blacklisting service. The second has 50,632 3-hourly satellite rainfall estimates at 576,000 locations.
