"A very important concept in object-oriented design, inheritance, refers to the ability of one class (child class) to inherit the identical functionality of another class (super class), and then add new functionality of its own. (In a very non-technical sense, imagine that I inherited my mother's general musical abilities, but in my family I'm the only one who plays electric guitar.) To model inheritance on a class diagram, a solid line is drawn from the child class (the class inheriting the behavior) with a closed, unfilled arrowhead (or triangle) pointing to the super class. Consider types of bank accounts: Figure 4 shows how both CheckingAccount and SavingsAccount classes inherit from the BankAccount class.
Figure 4: Inheritance is indicated by a solid line with a closed, unfilled arrowhead pointing at the super class." [ibm.com/ developerworks/ rational/ library/ content/ RationalEdge/ sep04/ bell/ index.html]

"Package diagrams can use packages containing use cases to illustrate the functionality of a software system.
Package diagrams can use packages that represent the different layers of a software system to illustrate the layered architecture of a software system. The dependencies between these packages can be adorned with labels / stereotypes to indicate the communication mechanism between the layers.
When To Use
- It is used in large scale systems to picture dependencies between major elements in the system
- Package diagrams represent a compile time grouping mechanism." [Package diagram. Wikipedia]
