    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.
