Data Science with Python | March 22nd - April 9th | Vaishali Balaji

Some of the challenges Data Scientists face in the real world are:
•Data quality doesn’t conform to the set standards
•Data integration is a complex task
•Data is distributed into large clusters in HDFS, which is difficult to integrate and analyze
•Unstructured and semi-structured data are harder to analyze
Want to know little bit more on these things, please clarify
