What is data science?
An Era of Explosion of data…
Data is increasingly cheap and ubiquitous. We are now digitizing analog content that was created over centuries and collecting myriad new types of data from web logs, mobile devices, sensors, instruments, and transactions. IBM estimates that 90 percent of the data in the world today has been created in the past two years. At the same time, new technologies are emerging to organize and make sense of this avalanche of data. We can now identify patterns and regularities in data of all sorts, both structured and unstructured.
Data Scientists are Big data wranglers. They take an enormous mass of messy data points and use their formidable skill in math, statistics and programming to clean , massage and organize them. Then they apply all their analytic powers and domain knowledge to uncover hidden solutions to business challenges.
A data scientist is someone who is better at statistics than any software engineer and better at software engineering than any statistician . This is further complemented by his domain knowledge and business understanding.
