Object-Oriented Analysis And Design (Exam 2)

Front 1

B contains A. B is:

Back 1

Creator

Front 2

B aggregates A. B is:

Back 2

Creator

Front 3

B keeps lis of A. B is:

Back 3

Creator

Front 4

B has constructors for A. B is:

Back 4

Creator

Front 5

This principle means that responsibility is best left to the one who knows best.

Back 5

Information Expert

Front 6

This principle supports low dependency and low-change impacts as well as increases re-use.

Back 6

Low coupling

Front 7

Common forms of coupling (5):

Back 7

- x has an attribute of y
- x calls services of y

- x is direct or indirect subclass of y

- x has method w/parameter, local variable or return type of y

- x implements interface of y

Front 8

Four forms of visibility

Back 8

1) Attribute visibility

2) Parameter visibility

3) Local visibility

4) Global visibility

Front 9

This principle allows you to handle alternatives based on type.

Back 9

Polymorphism

Front 10

This principle uses <<interface>> and <<extends>>

Back 10

Polymorphism

Front 11

This principle means creating an artificial or convenience class that does not represent a problem domain concept.

Back 11

Pure fabrication

Front 12

This principle allows you to avoid direct coupling between two or more things.

Back 12

Indirection

Front 13

This principle calls for identifying points of instability and assigning responsibilities to create a stable "interface" around them.

Back 13

Protected variations

Front 14

If it works with a base class it should work with its subclasses without surprise.

Back 14

Liskov substitution principle

Front 15

Don't talk to strangers

Back 15

Law of Demeter
