DEPENDENCIES
- Defined by an "#IMPORT"
Dependency Hierarchy
- Ideal design, but not always practical.
Dependency Cycles
- Usually BAD
- Breaks Modularity
- Not necessarily bad between classes in the same package (thats what packages are for)
Tightly Coupled
- 2 entities depend on one another in a close cycle
Loosely Coupled
- Larger Dependency Cycle that may include more classes

Class Dependency Analyzer
This tool goes through your code and illustrates your dependency structure. It also shows you where the best points are to break a dependency.
