Question 5
-
In a MongoDB database for an online bookstore, you're designing a data model to handle books, authors, and reviews efficiently, considering a complex scenario involving relationships and potential data skew due to varying numbers of reviews per book. Given the requirements:
Each book can have multiple authors.
Each author can write multiple books.
Books can have a large number of reviews, but most have a few or none, creating potential data skew.
The application frequently queries books with their authors and a sample of reviews to avoid performance issues due to data skew.
How should you model the relationships among books, authors, and reviews to optimize for query performance and data management?
