Normalisation in NoSQL in Mongo DB

Question

The first table is for products, how would I normalize this data.

• asin - ID of the product, eg 1574571931
• categories - list of categories the product belongs to
• description – description of product
• title - name of the product
• brand – brand name of the product

• price - price in US dollars (at time of crawl)
• salesRank - sales rank information. The better the sales, the lower the rank.
• imUrl - url of the product image
• related -

The second table is for reviews and how would I normalize this table as well.

• reviewerID - ID of the reviewer, eg A2Y113PST5WPPF
• asin - ID of the product, eg 1574571931
• reviewerName - name of the reviewer
• helpful - helpfulness rating of the review, eg 2 out of 3 found review helpful
• reviewText - text of the review
• overall - rating of the product
• summary - summary of the review
• unixReviewTime - time of the review (unix time in seconds)
• reviewTime - time of the review (raw)

What is the process of normalization and how can I organize the above 2 tables?

Answer 1

Normalization--a strictly logical process--is the same whether the target platform is a SQL dbms, a large scale C++ program, or a nosql database.

Following the normalization procedures in any good, college-level textbook, normalize every relation to 5NF. Then translate the results to your target platform. (You'll often have to translate declarative code to procedural code.)
