Data science today is considered a lucrative career and has immense opportunities for people who have all the necessary skills in balanced proportion and are able to apply them practically. No matter what kind of data that you come across, it always has a data scientist behind it working hard to make your job easier and give you solutions to your never ending doubts. Also to become a data scientist you need to have a solid grasp on statistics, mathematics, analytics, machine learning, etc as well as communication skills and business acumen to spread your findings to business and IT firms. Data scientists are found in all the applications where data is involved, which is currently in almost all fields.
DATA SCIENCE LANGUAGES:
This in demand course has some necessities which include having programming knowledge. Some of the languages which data scientists usually prefer are: Python- It is popular choice due to the amount of libraries and advantages and easy to learn, Java- because of its demand amongst software engineers for development, R-It is one of the most frequently used tools, Julia- high level dynamic programming language, SAS, SQL, MATLAB.
ROLE OF DATA SCIENTISTS IN INDUSTRY:
The roles and responsibilities of data scientist are vast and varied; there are lots of job titles where they can fit the bill. It is necessary to have the business acumen to go a long way in this field. A good data scientist must have knowledge of database administration, data cleaning and integration along with processing. It should be your prime concern to master data analysis if your math is not strong.
