Object class relationship

Define Object Modeling

Object modeling is a technique for identifying objects within the system environment and the relationships between those objects

To show who does what in an activity diagram you would divided it int ______

Partitions

Polymorphism

_________ means "many forms." Applied to object-oriented techniques, it means that the same named behaivor may be completed differently for different objects /classes

Polymorphism

______ diagrams graphically depict how objects interact with each other via messages in execution of use case or operation. They illustrate how message are sent and recievd between objects and in what sequence.

Sequence

persistent

An aggregation relationship is also called as a(n)_________

whole/part relationship

On an acitivity diagram a subactivity indicator indicates a separate activity diagram

True

Use case diagrams graphically depict the interactions between the system and external system users. In other words, they graphically describe who will use the system and in what ways the user expect to interact with system

True

The ____ is a set of modeling conventions that is used to specified or describe a software system in terms of objects (UML)

UML

In an acitivity diagram black bar with two or more flows comming in an one flow going out is called a ______

join

A(n) _______ is a set of objects that share the same attributes and behavior. It is sometimes referred to as an object class. Class

Class

_____ diagrams are similar to sequence diagrams but do not focus on the timing or sequence of messages. Instead they present the interaction or collaboration between objects in a network format.

Collaboration

D) System Sequence Diagram

Define the term polymorphism. give an example

Polymorphism means "many forms" Applied to object-oriented techniques, it means that a behaivor may be completed for different objects/class Door and Window different behavior close

An activity diagram can be used to model logic with the system

True

_______ diagrams are used to graphically depict the sequential flow of activities of either a business process or a use case. They also be use to model action s that will be performed when operation is executing as well as the result of those actions.

(Activity)

_______diagrams depict the system's object structure. They show object classes that the system is composed of as well as the relationship between those classes

(Class )

________diagrams are similar to class diagrams, but instead of depicting object classes, they model actual object instances showing the current values of the instance's attributes.

(Object)

Explain the concept of message sending for objects/ classes

A messages is passed when one object invokes another object's method (behavior) to request information or some action
