Design-Pattern

The difference between splitting code by technical layers (horizontal) and by features or domains (vertical). Trade-offs and selection criteria for each approach.

Layered architecture separates code into horizontal layers by technical responsibility. A summary of the four-layer structure, dependency direction rules, and how DIP decouples layers.

A pattern for switching from full cache refresh to incremental refresh. Separating data by update frequency and applying change detection reduces network costs.
