Study Notes
Systems Analysis and Design
- Systems analysis involves understanding and specifying what an information system should accomplish.
- Systems design involves defining and describing the detailed system that solves the identified need.
Systems Analysis Example
- Understanding the problem: Analysts gather information from stakeholders (e.g., warehouse staff, managers, suppliers) to understand existing processes, pain points, and requirements.
- Identifying system objectives: Define what the system should achieve, such as tracking inventory, triggering reorders, and providing reports.
- Documenting requirements: Create a requirements document detailing system functionality, user roles, processes, and integration needs.
Systems Design Example
- Defining system architecture: Choose the technical architecture, like cloud-based databases or web applications.
- Detailed design of components: Each part of the system (e.g., inventory management module) is designed with specific forms, tables, and features.
- Designing the database: Create a database structure to store data like product information, supplier details, and order history.
Unified Modeling Language (UML)
- UML is a standardized language for specifying, visualising, and documenting the design of information systems.
- Actors represent end users or other systems that interact with the system.
- Primary actors initiate use cases and interact with the system.
- System boundary defines the limits of the application, separating internal components from external interactions.
- Automation boundary separates computerized system components from user interactions.
Event Decomposition Technique (EDT)
- Identify events: Recognize external events (initiated by external actors), temporal events (triggered by time), and state events (triggered by internal state changes).
- Naming use cases: Assign a use case to each event, describing the system’s response.
- Benefits of EDT: Includes temporal and state events, breaks down processes into elementary business processes, focuses on core functions.
- Example events:
- Temporal Event: Automatically finalize class lists on a predetermined date.
- State Event: When a course section is full and the waitlist reaches a specific number, create a new section.
Use Case Diagrams
- Generalization: Used to show that a specialized use case is a particular way to achieve the goals of a more general use case.
- Scope of a use case:
- Primary use case: A logical unit of functionality, typically performed by one person, resulting in a consistent data state and delivering business value.
- Secondary use case: A refinement of the primary use case, potentially including or extending it.
- Structure of a use case: Describes system behavior from the user's perspective, outlining user actions and system responses without delving into implementation details.
- «include» relationship: Allows steps from one use case to be included in another to represent common sequences.
- **When to use «include»: ** Identify common steps and extract them into separate Use Cases.
