From tight coupling to loose coupling - best practices
Learn about software coupling - the degree of interdependence between modules. Understand different coupling types and achieve loosely coupled, maintainable code.
| Type | Coupling Level | Description |
|---|---|---|
| Content | Highest (Worst) | Direct access to internals |
| Common | High | Shared global data |
| Control | Medium | Pass control information |
| Stamp | Medium | Pass data structures |
| Data | Low | Pass only needed data |
| Message | Lowest (Best) | Communication via messages |
