Study Notes
Object-Oriented Systems Mid-Term
- Class diagram: A box on a class diagram represents a set of attributes
- Agile Development: Iterative development is not the same as Agile development
- System Analyst: A system analyst plans, captures the vision, and understands the needs of a new system.
- Closed-ended questions: Limit answers to a set of choices, speed up the interview process
- UML: Unified Modeling Language
- Technology Architecture: The combination of information systems and the hardware infrastructure
- Successful Interview: Requires preparation
- State Event: An event triggered by something happening outside the system
- Timed Event: An event that occurs by reaching a point in time
- User Stories vs Use Cases: Differ in the amount of detail captured and the focus
- Event Decomposition Technique: Identifies use cases based on external, temporal, and state events
- Association Class: Frequently required for a many-to-many relationship
- UML Class: Not a set of objects. It's a classification of objects.
- State Machine Diagram: Documents the states and transitions of an object
- Cardinality of a Class: Not a measure of the number of objects in the class
- Semantic Net: Doesn’t illustrate individual objects within a class diagram
- Activity Diagram: An oval in an activity diagram indicates an embedded use case.
- Object-Oriented Modeling Advantages: Developing new models helps gain deeper understanding of user requirements, and ensures consistency in the requirements
- Preconditions in a Use Case: Describe what business conditions must occur before the use case is invoked.
- System Sequence Diagram: A box refers to a class of objects.
- Activity Diagram: A separate use case can be used as part of the workflow
- CRUD Technique: Not the best use for generating new use cases
- Design Activities Output: A set of diagrams and documents describing the solution system
- Implementation Objective: To integrate the application components
- Package Diagrams: Used primarily when designing software classes
- Design Activities: Database design, environment design, interface design, and security and controls design are all design activities that pervade all other design activities.
- Database Design: Often requires an analyst's skills to make decisions about field sizes and characteristics
- Privileged User: A user with special security and access to a system, such as the right to assign passwords, is called a privileged user.
