Implementation plan:

1. Document-based databases (e.g., MongoDB)
   • Schema-less / flexible schema
   • Documents and collections
   • When to use: varying structure, rapid prototyping, nested data
2. Key-value stores (e.g., Redis)
   • Simple key-value pairs
   • In-memory, extremely fast
   • When to use: caching, session storage, rate limiting
3. Comparison: relational vs document vs key-value
4. Choosing the right database for the use case
5. Polyglot persistence — using multiple databases in one system
