Study Notes
Use Case Diagram
- Illustrates system functions with respect to actors interacting with the system.
Workflow
- Visual representation of processes to guide user interactions and system responses.
Functional Requirement
- Focuses on user interface, functionality, and business needs.
User Interface (UI) Requirement Study
- UI facilitates interaction between humans and machines, crucial for application usability.
- Also known as the front-end of the system, it allows for:
- Input: user manipulation of the system.
- Output: system feedback on user actions.
- Poor user interface design negatively impacts first impressions.
Mock-up Screen Design
- Consists of a detailed description of screen components, including:
- Field name, control type, data type, default values, and mandatory fields.
- Editable status, maximum length, value, description, and validation requirements.
Use Case/Function Study
- Purpose: Provides an overview of the use case's main idea.
- Actor: Individual interacting with the use case.
- Pre-condition: System states pre-dating the use case initiation.
- Trigger: Event kick-starting the use case.
- Basic Flow: Sequence of actions when everything functions correctly.
- Alternative Flow: Sequence when errors occur.
- Post-condition: Possible states of the system post-use case.
- Business Rule: Defines or restricts certain business aspects.
Example - Client Creation Use Case
- Purpose: To add a new client to the system.
- Actor: Practice Business User (e.g., Manager, Administrative, or Sales roles).
- Pre-conditions include user login and necessary permissions (Full control - Client Management).
- Trigger involves user selecting the 'Client Creation' submenu or button.
Requirements Importance
- Establishing clear requirements is essential for successful software development.
Requirement Classification
- Various documents outline requirements:
- High-Level Requirement (HLR) Document / User Requirement Definition (URD).
- Use Case Document.
- Software Requirement Specification Document.
Requirement Types
- Divided into:
- Functional Requirements: Define system functionalities important to the business flow (e.g., data manipulation, reporting, security access).
- Non-functional Requirements: Describe system behavior constraints, categorized as:
- Quality, performance, design, environmental/platform, and process constraints.
Quality Constraints
- Reflects the desired quality attributes of a system.
