Data Science is the way to collect, store and interpret data in the correct manner. Data science provides the tools and framework for better business decision making. Two beautiful things which i love about data science , first is the fact that it draws from multiple disciplines , one needs to have business knowledge, programming skills, statistics, good communication skills and some knowledge of systems.
Secondly , it replaces the gut feel part of business decision making. Before democratization of software and cheap computing power, same decisions were being made based on past experience by business managers, Data science quantifies that and gets optimal solutions.
