Episode notes
Focus on Real Problem First
- A common software design mistake is jumping to solutions like class hierarchies without understanding the real problem.
- Focusing on the actual problem you are trying to solve generates clearer, more fitting designs such as representing many-to-many relationships directly.
University OOP Design Example
- Eric shares his university experience where object-oriented design taught to turn nouns into classes and verbs into methods.
- This often leads to complicated designs trying to sync many-to-many relationships like students and courses.
Ask How to Solve Without Code
- Before coding, drop habitual recipes like drawing boxes and arrows and ask how you would solve the problem with paper and pencil.
- This helps clarify the actual problem and avoid overcomplicated or inappropriate models.
