A modern data ecosystem includes interconnected, independent and continually evolving entities. Various forms of raw data are pulled from their original sources into a data repository which make up part of this ecosystem.

We can say that there are 4 types of data analysis which are Descriptive Analytics (“What Happened”), Diagnostic (“Why?”), Predictive (“What will happen next”), and Prescriptive (“What should be done about it”).
