Study Notes
Here are the study notes in bullet points:
Non-Functional Requirements of a Software System
- Non-functional requirements focus on the technical design of the software system.
- Examples: operating systems, network protocols.
Use Cases and Actors
- Use cases represent a sequence of actions that the system performs in response to an external event to achieve a specific goal or objective.
- Actors are people, organizations, or systems that interact with the software system being developed.
- There are three types of actors: primary actors, supporting actors, and offstage actors.
Use Case Model
- The use-case model is a model that shows how users interact with the system to solve a problem.
- The use-case model defines the user's objective, the interactions between the system and the user, and the system's behavior required to meet these objectives.
Use Case Diagram
- A use case diagram is a graphical representation of the relationships between actors and use cases.
- Components of a use case diagram include actors, use cases, and associations between them.
Inception Phase of Object-Oriented Analysis and Design (OOAD)
- The inception phase involves gathering information and understanding the requirements for a new software project.
- Activities in the inception phase include:
- Identifying the problem to be solved
- Defining the scope of the project
- Identifying stakeholders
- Establishing project goals and objectives
- Creating the initial set of requirements
Artifacts in Inception
- Artifacts in inception include:
- Vision and Business Case
- Use-Case Model
- Supplementary Specification
- Glossary
- Risk List and Risk Management Plan
- Prototypes and proof-of-concepts
- Iteration Plan
- Phase Plan and Software Development Plan
- Development Case
Requirements
- Requirements are high-level descriptions of a particular system service, constraint, or detailed specification generated during the requirements gathering process.
- Types of requirements include:
- Functional requirements
- Non-functional requirements
- User requirements
- System requirements
- Design requirements
- Domain requirements
Test your knowledge on the software development life cycle phases, requirements, and technical design concepts. Questions cover topics such as supplementary specifications, non-functional requirements, and design requirements.
