Study Notes
Inception Phase in OOAD
- Inception is the first phase of Object-Oriented Analysis and Design (OOAD) methodology
- It involves gathering information and understanding the requirements for a new software project
- The main objective is to establish the scope of the project, identify stakeholders, and define initial requirements
- Activities in inception phase:
- Identifying the problem
- Defining the scope
- Identifying stakeholders
- Establishing project goals and objectives
- Creating the initial requirements
Artifacts in Inception
- Vision and Business Case: describes high-level goals and constraints, business case, and executive summary
- Use-Case Model: describes functional requirements
- Supplementary Specification: describes non-functional requirements
- Glossary: defines key domain terminology and data dictionary
- Risk List and Risk Management Plan: describes risks and ideas for mitigation
- Prototypes and Proof-of-Concepts: clarifies vision and validates technical ideas
- Iteration Plan: describes the first elaboration iteration
- Phase Plan and Software Development Plan: low-precision guess for elaboration phase duration and effort
Requirements in OOAD
- Requirements are high-level descriptions of a system's services, constraints, or detailed specifications
- Types of requirements:
- Functional requirements: describe specific functions and features of the software system
- Non-functional requirements: specify characteristics of the software system not related to functionality
- Other types of requirements:
- User requirements: describe the needs and expectations of end-users
- System requirements: describe hardware and software infrastructure needed for the software system
- Design requirements: describe technical design of the software system
- Domain requirements: specific to a particular category or domain of projects
Use Cases and Use Case Model
- A use case represents a sequence of actions that the system performs in response to an external event to achieve a specific goal or objective
- Use Case Model:
- Defines how users interact with the system to achieve specific objectives
- Consists of actors, use cases, and associations between them
- Uses a hierarchical structure to organize use cases based on level of abstraction
- Components of Basic Model:
- Actors: people or external systems that interact with the software system
- Use Cases: define how actors use the system to achieve specific objectives
- Associations: define relationships between actors and use cases
Use Case Diagram
- A graphical representation of the use case model
- Components:
- Actors: stick figures representing users
- Use Cases: horizontally shaped ovals representing functionality
- Associations: lines between actors and use cases
- System Boundary Boxes: boxes that set the system scope for use cases
- Packages: group similar types of use cases
Activity Diagram
- A visual representation of a series of actions or flow of control in a system
- Often used in business process modeling
- Can describe the steps in a use case diagram
- Symbols:
- Activity nodes: rounded rectangles representing actions
- Control flow arrows: connecting activity nodes
- Decision nodes: diamonds indicating branching points
- Guards: conditions for flows
- Merge nodes: combine multiple flows into one
