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
