Analysis And Design 12

Front 1

instantiation

Back 1

creation of an object based on the template provided by the class definition

Front 2

object oriented design

Back 2

the process to identify the set of classes, their methods, and their messages required to execute a use case

Front 3

stereotype

Back 3

a way of categorizing a model element by its characteristics indicated by guillemets(<< >>)

Front 4

entity class

Back 4

a design stereotype for a problem domain class

Front 5

persistent class

Back 5

an entity class whose objects must continue to exist after a system is shut down

Front 6

boundary or view class

Back 6

a class that exists on a system's automation boundary, such as a user interface or a system interference class

Front 7

controller class

Back 7

a class that mediates between boundary classes and entity classes, acting as a switchboard between the boundary or view layer and domain layer

Front 8

data access class

Back 8

a class that is used to retrieve data from a database

Front 9

visibility

Back 9

a notation that indicates(by plus or minus sign) whether an attribute can be directly accessed by another object

Front 10

method signature

Back 10

a notation that shows all the information needed to invoke or call the method

Front 11

class-level method

Back 11

a method that is associated with a class instead of with object of the class

Front 12

class-level attribute

Back 12

an attribute that contains the same value for all objects in the system

Front 13

navigation visibility

Back 13

a design principle in which one object has a reference to another object and can thus interact with it

Front 14

Object Responsiblity

Back 14

a design principle in which objects are responsible for carrying out system processing

Front 15

separation of responsibilities

Back 15

a design principle that recommends segregating classes into separate packages or groupings based on a primary focus of processing responsiblity

Front 16

protection from variations

Back 16

a design principle in which parts of a system that are unlikely to change are segregated from those that will

Front 17

Indirection

Back 17

a design principle in which an intermediate class is placed between two classes to decouple them but still link then

Front 18

coupling

Back 18

a qualitative measure of how closely the classes in a design class diagram are linked

Front 19

cohesion

Back 19

a qualitative measure of the focus or unity of purpose within a single class
