NoSQL Databases (DynamoDB, Cosmos DB)

Part of the Cloud Computing Roadmap.

Summary

Fully managed, highly scalable key-value/document databases designed for massive scale and low-latency access — a different data modeling approach from relational databases, optimized for specific access patterns.

How to Learn This

  • 1Create a simple table in a managed NoSQL service and perform basic CRUD operations.
  • 2Learn why NoSQL data modeling starts from your access patterns, not your entities, unlike relational design.
  • 3Understand when NoSQL's flexibility is worth the trade-off of weaker query flexibility.
