Data analysis

Data analysis, also known as analysis of data or data analytics, is a process of inspecting, cleansing, transforming, and modeling data with the goal of discovering useful information, suggesting conclusions, and supporting decision-making.
Analysis (ana "up, back, throughout" + lysis "a loosening,") is the process of breaking a complex topic or substance into smaller parts in order to gain a better understanding of it. The technique has been applied in the study of mathematics and logic since before Aristotle (384–322 B.C.), though analysis as a formal concept is a relatively recent development.[1]
Data mining
 is a particular data analysis technique that focuses on modeling and 
knowledge discovery for predictive rather than purely descriptive 
purposes, while business intelligence covers data analysis that relies heavily on aggregation, focusing on business information.[1]
