Report– single spaced 3 page, excluding reference properly cited.

Read the articles and write a review to report what you have learned.

The report should also answer the following four questions:

(a) Summarize your understanding about Big data.

(b) What can you say about schemas in Big data?

(d) What is NewSQL? How does it differ from SQL and NoSQL?

Answers to these questions should be a part of the report, not the complete report itself.
