Episode notes
Product and Sum Types in Data Modeling
- Products and sum types are fundamental concepts in data modeling, especially in functional programming.
- They help create precise data structures that accurately represent the domain.
Two-Step Approval Process Scenario
- Eric Normand presents a scenario involving a two-step approval process to illustrate the pitfalls of poorly designed data models.
- Invalid states arise from using a simple product type (tuple) where a more nuanced approach is needed.
Product vs. Sum Types
- Product types multiply possibilities, exemplified by tuples, while sum types add possibilities, like enums or eithers.
- The choice depends on whether you combine independent options or represent mutually exclusive states.
