Study Notes
Object-Oriented Programming Concepts
- Polymorphism refers to the ability of an object to take on multiple forms, depending on the context in which it is used.
UML Diagrams
- A Project Manager typically produces a Use Case Diagram.
States and Actors
- Initial State is a specific state in a system.
- An Actor is an entity that interacts with a system, but is not part of the system itself.
Inheritance and Relationships
- The term used to describe the relationship between a Superclass and its Subclass is Inheritance.
Actors and Roles
- A Secondary Actor is an entity that is not a primary user of the system, but still interacts with it.
Data Flow Diagrams
- A Data Store should be visually represented as a rectangle with an open top in a DFD.
UML Behavioral Diagrams
- The diagram options (not provided) that are not UML behavioral diagrams are EXCEPT for...
Encapsulation
- Encapsulation refers to the concept of bundling data and its associated methods that operate on that data within a single unit, making it harder for other parts of the program to access or modify the data directly.
Generalization Association
- Generalization Association is a transitive association, meaning the relationship between instances of one class can be extended to instances of another class through a chain of associations involving intermediate classes.
