Episode notes
Document Model Maps To Application Objects
- MongoDB stores data as JSON-like documents that map closely to application objects instead of normalized tables.
- This document model reduces impedance mismatch with object-oriented applications and simplifies development.
Embed Related Data In One Document
- Documents can contain nested objects and arrays so a single document can represent an entire business entity like an order.
- Storing related data together avoids multi-table transactions for frequently accessed aggregates.
Evolve Schema Incrementally
- Start inserting data without rigid schema and evolve fields as application needs change.
- Use arrays or new fields later instead of heavy migrations required by relational schemas.
