Episode notes
Data Modeling
- Data modeling represents entities, attributes, and relationships using data structures.
- Functional programming uses this in contrast to object-oriented programming's class-based approach.
Relationships over Entities
- In many problems, relationships between entities are more important than the entities themselves.
- Representing these relationships as first-class citizens in your model can be advantageous.
Graph Representation
- Eric Normand gives an example of representing a graph by focusing on edges instead of nodes.
- This approach makes tasks like counting edges and building indexes more efficient.
