Difference Between Data Science and Data Mining is pretty much complicated and as well as interesting. Data Science is a field that comprises of everything that related to data cleaning, and analysis. Data Mining is the process of gathering information stored in the database that was previously obscure and unknown.
There are not so many difference between machine learning and data science. Machine learning engineers build machine learning systems. Data scientists conduct research to generate ideas about machine learning projects and perform analysis to understand the metrics impact of machine learning systems.
R vs Python, which one is better for Data Science, finding the best one is always a heavy task. Python and R both the languages have their own features.
