Hi Rithika,

I think you are asking a wrong question, there is no point of difference between Data System and data science as they are both different sector things. One is technology and the other is the storage of technology driven things. You ask the difference between Data Science and Big Data or  between Data Science and Data Analytics or between Big Data and Data Analytics.

Please let me know your correct question so that I can help you in a better way.

Feel free to ask doubts in the Comment Section.

I hope this information helps you.

Good Luck!

A data system is simply a place were you store a data. The data science is the study of data using methods,processes, and insights that corresponds to structured or unstructured data. The difference is that data systems are actual objects and data science are methods.
