Data Modeling¶
Level: L2 | Domain: devops
Data modeling is the discipline of designing how data is structured, related, and accessed within a database. Good data models encode business rules at the schema level, optimize for primary query patterns, and evolve gracefully as requirements change.
Whether you are normalizing a relational schema, designing DynamoDB partition keys, or structuring MongoDB documents, data modeling decisions have outsized impact on query performance, application complexity, and operational cost.
