    Study Notes

    Architectural Models

    • Architectural models aid in comprehending system structure and component interactions.
    • Functional decomposition simplifies a system's functionality into smaller, manageable functions or modules.

    Functional Modeling

    • Focuses on what a system does rather than how it accomplishes it.
    • User perspective is crucial to ensure the system meets specified requirements.
    • Use Cases describe user-system interactions to achieve specific goals.
    • Activity Diagrams showcase the flow of activities and actions within a system.
    • Functional Flowcharts depict the operational flow and functions within the system.

    Structural Modeling

    • Represents system components, their relationships, and interactions.
    • Essential for understanding system architecture and ensuring effective collaboration among parts.
    • Components encapsulate functionalities, which can be software modules or hardware units.
    • Relationships include associations, dependencies, generalizations, and aggregations.
    • Class diagrams illustrate relationships, notable for showing connections such as Customer and Order classes.

    Deployment and Maintenance

    • Deployment occurs post-testing when a system is installed, configured, and made available for users.
    • Maintenance includes system monitoring, updates, and enhancements to address changing requirements.

    Behavioral Modeling

    • Describes system behavior and responses to stimuli.
    • Utilizes state diagrams, sequence diagrams, and collaboration diagrams for dynamic system illustration.

    Data Modeling

    • Focuses on representing system data requirements and structures.
    • Common techniques include Entity-Relationship Diagrams (ERDs) and data flow diagrams.
    • Normalization structures data into forms (1NF, 2NF, 3NF) defining organizational rules.

    Dimensional Modeling

    • Used primarily in data warehousing for organizing data into facts and dimensions.
    • Facts refer to quantitative data stored in fact tables, while dimensions are descriptive attributes stored in dimension tables.

    System Design

    • A crucial phase where analysis phase requirements inform the creation of detailed blueprints for system construction.
    • Involves defining architecture, components, modules, interfaces, and data needed to meet specified requirements.

    Key Aspects of System Design

    • Architectural Design outlines the overall system structure and high-level components.
    • Common architectural styles include client-server, layered architecture, and microservices.
    • User Interface Design emphasizes creating intuitive, user-friendly interfaces that enhance usability.
    • Security Design integrates considerations to protect the system against unauthorized access and data breaches.
