19 Questions
What is the main purpose of using System Sequence Diagrams (SSDs) in use case realization?
To visualize the sequence of events that occur during system functionality implementation
What do preconditions specify in an operation contract?
The conditions that must be true before the operation is executed
Which OOA artifact defines the behavior of a method or operation of a class?
Operation Contracts
What is the role of Operation Contracts in object-oriented analysis and design (OOAD)?
To verify that a method is implemented correctly
How do Postconditions differ from Preconditions in an operation contract?
Postconditions specify the conditions that must be true after the method has executed, while Preconditions specify conditions before execution.
In operation contracts, what do Invariants specify?
The properties that should be preserved or maintained during method execution
What is the purpose of Operation Contracts in generating test cases?
To ensure that a method behaves correctly in various situations
How do object diagrams differ from system sequence diagrams (SSDs) in representing system functionality?
Object diagrams represent specific instances of objects and their relationships, while SSDs visualize sequence of events during system functionality implementation.
Which element in an operation contract defines the name and parameters of the operation?
Header
What do preconditions specify in an operation contract?
The conditions that must hold true before a method is executed
Which part of an operation contract defines the name and parameters of the operation?
Header
How do Invariants differ from Preconditions in an operation contract?
Invariants specify the properties that should be preserved during method execution
What is the main purpose of an Operation Contract in object-oriented analysis and design (OOAD)?
To specify the behavior of a method or operation of a class
What do Postconditions specify in an operation contract?
The conditions that must hold true after a method has completed successfully
How do System Sequence Diagrams (SSDs) help in use case realization?
By representing the specific implementations of system functionality
Why are Operation Contracts considered essential in object-oriented analysis and design (OOAD)?
To identify preconditions and postconditions for a method or operation
In object diagrams, what do System Sequence Diagrams (SSDs) help represent?
The specific instances of objects and their relationships
What is represented by an SSD in object diagrams?
The different files stored on a storage device and their relationships to users and folders
What is the role of SSDs in visualizing specific object instances?
To visualize object instances and their attributes and relationships
