What is the primary difference between SQL and NoSQL modeling in this skill?

The skill teaches the 'Query-First' approach, where data is modeled specifically to serve pre-defined access patterns rather than normalized entities.

Which databases are supported by the NoSQL Expert skill?

This skill focuses on distributed wide-column and key-value stores, specifically Amazon DynamoDB, Apache Cassandra, and ScyllaDB.

Can this skill help with database migration projects?

Yes, it assists developers in making the mental shift from ACID-compliant relational models to BASE-compliant distributed systems, including eventual consistency strategies.

How does this skill help with DynamoDB performance?

It provides guidance on implementing single-table design and adjacency lists, optimizing GSI usage, and managing WCU/RCU consumption to prevent hot partitions.
