Study Notes
Inception in OOAD
- Inception is the first phase of Object-Oriented Analysis and Design (OOAD) methodology, which involves gathering information and understanding the requirements for a new software project.
- The main objective of inception is to establish the scope of the project, identify the stakeholders, and define the initial set of requirements.
- Inception phase involves several activities, such as:
- Identifying the problem
- Defining the scope
- Identifying stakeholders
- Establishing project goals and objectives
- Creating the initial requirements
Artifacts in Inception
- Artifacts in inception are the outputs of the inception phase.
- The common inception artifacts are:
- 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 the high-level descriptions about a particular system, services, constraints, or to a detailed specification that are generated during the requirements gathering process.
- Requirements are capabilities and conditions needed by a user to solve a problem or achieve an objective.
- Types of requirements:
- Functional Requirements
- Non-Functional Requirements
- Categories of requirements:
- User Requirements
- System Requirements
- Design Requirements
- Domain Requirements
Use Cases and Use Case Model
- Use cases are a technique used to capture functional requirements of a software system.
- 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.
- A use case typically consists of four elements:
- Actors
- Use Case Name
- Description
- Preconditions and Postconditions
- Use Case Model:
- The Use-case model is defined as 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
- Use Case diagrams are one of the five diagrams in the UML for modeling the dynamic aspects of systems.
- The UML provides the use case diagram to illustrate the names of use cases and actors, and the relationships between them.
- Use case diagram components:
- Actors
- System
- Goals
- Use cases
- Associations
- Use case diagram symbols and notation:
- Use cases: Horizontally shaped ovals
- Actors: Stick figures
- Associations: A line between actors and use cases
- System boundary boxes: A box that sets a system scope to use cases
- Packages: A UML shape that allows you to put different elements into groups
Activity Diagram
- An activity diagram visually presents a series of actions or flow of control in a system similar to a flowchart or a data flow diagram.
- Activity diagrams are often used in business process modeling.
- Activity diagram symbols:
- Activity nodes: Rounded rectangles
- Control (Activity) flow arrows: Connect the activity nodes
- Decision nodes: Diamonds
- Merge nodes: Diamonds
- Swimlanes: Organize activities and show the different actors or organizations involved in the process
- Synchronization: Fork node and join node
- Flow final nodes: Circle with a cross inside
- Object nodes: Rectangles
