An sequence diagram is

technology web technology

  1. a time-line illustrating a typical sequence of calls between object function members

  2. a call tree illustrating all possible sequences of calls between class function members

  3. a time-line illustrating the changes in inheritance and instantiation relationships between classes and objects over time

  4. a tree illustrating inheritance and relationships between classes

  5. a directed acyclic graph illustrating inheritance and instantiation relationships between classes and objects

Show answer
Correct Option: A

AI Explanation

To answer this question, you need to understand what a sequence diagram is.

Option A) A time-line illustrating a typical sequence of calls between object function members - This option is correct. A sequence diagram is a type of interaction diagram in UML that represents the interactions between objects in a system. It shows the sequence of messages or method calls between objects in a time-ordered manner.

Option B) A call tree illustrating all possible sequences of calls between class function members - This option is incorrect. A call tree is a different type of diagram that represents the hierarchy of method calls in a program. It is not specifically used to illustrate sequences of calls between class function members.

Option C) A time-line illustrating the changes in inheritance and instantiation relationships between classes and objects over time - This option is incorrect. While a sequence diagram can show interactions between objects, it does not specifically illustrate changes in inheritance and instantiation relationships between classes and objects.

Option D) A tree illustrating inheritance and relationships between classes - This option is incorrect. A sequence diagram does not typically illustrate inheritance and relationships between classes. It focuses on interactions between objects.

Option E) A directed acyclic graph illustrating inheritance and instantiation relationships between classes and objects - This option is incorrect. While a directed acyclic graph can be used to represent inheritance and instantiation relationships, it is not specifically used to create sequence diagrams.

The correct answer is A) a time-line illustrating a typical sequence of calls between object function members. This option is correct because a sequence diagram represents the sequence of messages or method calls between objects in a time-ordered manner.

In the UML notation, inside each class in a class diagram are printed

technology web technology

  1. its name, attributes, operations, and derived classes.

  2. its name, attributes and operations.

  3. its name, and attributes.

  4. its name, and operations.

  5. just its name.

Show answer
Correct Option: B

AI Explanation

To answer this question, we need to understand the UML notation used in class diagrams.

In the UML notation, each class in a class diagram typically includes the following information:

  • Its name
  • Its attributes (also known as properties or fields)
  • Its operations (also known as methods or functions)

Therefore, the correct answer is B) its name, attributes, and operations.

Let's go through each option to understand why it is correct or incorrect:

Option A) its name, attributes, operations, and derived classes - This option is incorrect because class diagrams do not typically include information about derived classes. They only include the name, attributes, and operations of the class itself.

Option B) its name, attributes, and operations - This option is correct because it includes all the necessary information about the class.

Option C) its name and attributes - This option is incorrect because it does not include information about the operations of the class.

Option D) its name and operations - This option is incorrect because it does not include information about the attributes of the class.

Option E) just its name - This option is incorrect because it does not include any information about the attributes or operations of the class.

Therefore, the correct answer is B) its name, attributes, and operations.

Key elements of the use-case diagram are:
