To explain Data Science in simple words: It is a study of where information is extracted from, what it represents and how it can be converted into a valuable source in the building of IT and Business approaches.
Data science is a field which is composed of statistics, mathematics, and computer science disciplines efficiently and incorporates techniques like cluster analysis, machine learning, visualization, and data mining.
In the past few years, Data Science has calmly spread to include organizations and businesses worldwide. It is widely used by astronomers, analytics, and research, geneticists, entrepreneurs as well as engineers.
A data scientist aims to transform data into knowledge, knowledge which is used to make rational decisions. They possess all three set of skills - Mathematics and Statistics, Machine Learning and Subject Matter Expertise. Patrons who are masters in all three skills are less in number. The three skills required for data science mastery are explained below:
Machine learning is a subfield of artificial intelligence based on statistics. It involves machines learning how to complete tasks without being explicitly programmed to do so. This part is explained in details further.
While everyone knows what math is, statistics is the study of data: how to collect, summarize and present it. The statistics part will be covered in details later on.
In general, a domain expert or subject-matter expert (SME) is an individual who is a specialist in a specific area or topic. An SME should also have basic knowledge of other technical subjects too. In Data Science an SME Provides industry/process-specific context for what the patterns identified by the algorithms and models mean.
Such Individuals who master all three skills are also called as Unicorn Data Scientist. Despite how rare unicorn data scientists are they are rapidly growing in demand. Also, there doesn't appear to be any end in sight for the growth of this demand. As a result, in the very near future, this specific set of skills will be in high demand, whether you're a data scientist or applying data science practices to your current job role. The rarity of data scientists combined with their high demand leads to much higher salaries for data scientists and IT professionals with similar skills.

Quora is a global platform for gaining knowledge through question and answers, Where people engage in discussions, ask questions and find resources on any topic virtually. This community aims at “the technical approach to extraction of knowledge from data.”
There exists a lot of articles on O’Reilly, which seem to be very interesting. They cover most of the articles related to artificial intelligence and data science written by experts and influencers in data science. Therefore, they sound technically strong and also share concepts which are advanced. O'Reilly is notable for putting on events, for example, Strata that help characterize the data science group.
Data Science Association is a non-profit group of professionals offering professional certification, education, meetups and conferences, and even “Code of Professional Conduct on Data Science,” this is a highly recommended community for professionals of data science.
