Compare and contrast data analysis with data mining.
Data analysis is the process of extracting, cleaning, transforming, modeling, and displaying data to acquire pertinent information that may be used to draw conclusions and determine the best course of action. Data analysis has been practiced since the 1960s. Huge amounts of knowledge are examined and evaluated in data mining, sometimes referred to as knowledge discovery in databases, to detect patterns and laws. It has been a trend word since the 1990s.
