NoSQL Data Modelling

NoSQL Data Modelling has two choices viz. Embedding (non-normalized) vs Referencing (normalized).

Aspects to choose:

• 1:1 relationship => Prefer Embedding
• 1-to-Many (small & bounded) => Prefer Embedding
• 1-to-Many (unbounded) => Prefer Referencing
• Volatility (frequently changing sub-documents) => Prefer Referencing
• Immense read-speeds needed => Prefer Embedding
