Art1P12Q3: Which principle states the goal of object orientated architecture and which states the primary mechanism?

Answer: The goal is stated by the Open Closed Principle and the primary mechanism is stated by the Dependency Inversion Principle.

Art1P14Q1: Where is the most common places that designs depend on concrete classes?

Answer: When instances are created.

Art1P14Q2: What is the Interface Segregation Principle?

Answer:

“Many client specific interfaces are better than one general purpose interface.”

Art1P16Q1: What means of organising a design has larger granularity than classes?

Answer: Packages.

Art1P16Q2: What are the three principles of package architecture?

Answer:

• The Release Reuse Equivalency Principle
• The Common Closure Principle
• The Common Reuse Principle

Art1P17Q1: What is the Release Reuse Equivalency Principle?

Answer:

“The granule of reuse is the granule of release.”

Art1P17Q2: What is the Common Closure Principle?

Answer:

“Classes that change together, belong together.”

Art1P17Q2: What is the Common Reuse Principle?

Answer:

“Classes that aren't reused together should not be grouped together.”

Art1P18Q1: Which package architecture principle or principles tends to advantage reusers and which tends to advantage maintainers?

Answer: Reusers are advantaged by the Release Reuse Equivalency Principle and the Common Reuse Principle. Maintainers are advantaged by the Common Closure Principle.

Art1P18Q2: Which package architecture principle or principles tends to make packages large which tends to make them small?

Answer: The Common Closure Principle tends to make large packages and the Common Reuse Principle tends to make small packages.

Art1P18Q3: Which package architecture principle or principles would architects tend to use in the early life of a system and which would they tend to use when the system had matured?

Answer: In early life, the Common Closure Principle tends to be used. When the system has matured the Release Reuse Equivalency Principle and the Common Reuse Principle tend to be used.

Art1P18Q4: What are the three principles of package coupling?

Answer:

• The Acyclic Dependencies Principle
• The Stable Dependencies Principle
• The Stable Abstraction Principle

Art1P18Q5: What is the Acyclic Dependencies Principle?

Answer:

“The dependencies between packages must not form cycles.”

Art1P21Q1: What are two methods for breaking a cycle in a package dependency structure?

Answer:

• Add a new package.
• Add a new interface that has all the methods that one package is dependant on and is implemented by the other package.

Art1P22Q1: Which package would an interface very often go in?

Answer: The package that uses it, rather than the package that implements it.

Art1P22Q2: What is the Stable Dependencies Principle?

Answer:

“Depend in the direction of stability.”

Art1P24Q1: What is the Stable Abstraction Principle?

Answer:

“Stable packages should be abstract packages.”
