    Study Notes

    System Design

    • The process of defining the architecture, components, modules, interfaces, and data for a system
    • Translates requirements identified during analysis into a blueprint for building the system

    Key Activities

    • Architecture Design: Defines the overall structure, including hardware, software, and network components
    • Detailed Design Specifications: Creates detailed documents outlining how each component functions
    • Database Design: Designs the schema and data models to support data storage
    • User Interface Design: Designs user interfaces that are intuitive and user-friendly
    • Prototyping: Develops prototypes for visualization and stakeholder feedback
    • Integration Planning: Plans how different system components will interact with each other and existing systems

    Relationship Between System Analysis and System Design

    • System analysis precedes design, identifying what the system needs to do.
    • Design focuses on how to achieve those requirements.
    • The analysis findings inform design decisions.
    • Both phases produce documentation that serves as a reference and guides the development process.

    Major Components of a System

    • Interrelationships: Components are interconnected, meaning one component's state can affect others.
    • Purpose: Every system is designed to achieve a specific goal.
    • Inputs and Outputs: Systems receive inputs from the environment, process them, and produce outputs.
    • Feedback Mechanisms: Systems can adjust and adapt based on their outputs to maintain stability or improve performance.

    Types of Systems

    • Open vs. Closed Systems: Open systems interact with the environment, closed systems do not.
    • Physical vs. Abstract Systems: Physical systems have tangible components while abstract systems involve concepts, processes, or methodologies.
    • Simple vs. Complex Systems: Simple systems have fewer components and interactions, while complex systems have many interrelated parts and behaviors.

    Types of Information Systems

    • Transaction Processing Systems (TPS): Handle day-to-day transactions (sales, receipts, payroll, inventory) and process large volumes of routine transactions.
    • Management Information Systems (MIS): Provide managers with tools to organize, evaluate, and manage departments. They generate reports based on data from TPS and aid in decision-making.
    • Decision Support Systems (DSS): Analyze large volumes of data and provide insights to support complex decision-making.
    • Executive Information Systems (EIS): Systems designed for senior executives, providing easy access to internal and external information relevant to their strategic goals. They often feature dashboards and visualization tools.
    • Customer Relationship Management Systems (CRM): Help organizations manage interactions with customers. They store customer data, track sales, and manage marketing campaigns.

    Boundaries

    • Every system has defined boundaries that distinguish it from its environment.

    Environment

    • Systems exist within an environment that can influence their operation.

    Hierarchy

    • Systems can be organized into hierarchies, with larger systems composed of smaller subsystems.

    Equifinality

    • A system can reach the same final state from different initial conditions and through different paths.

    Players in the System Game (Stakeholders)

    • Users: Interact with the system daily, provide input on requirements, and ensure the system meets their needs.
    • Business Analysts: Understand business needs and requirements. Act as a bridge between stakeholders and the technical team.
    • System Analysts: Responsible for the technical aspects of system design and implementation, analyze requirements, and ensure the system functions correctly.
    • Project Managers: Oversee the entire project, ensuring it is completed on time, within budget, and meets requirements.

    Required Skills of a Systems Analyst

    • Analytical Skills: Analyze complex problems, identify solutions, and make data-driven decisions.
    • Technical Proficiency: Knowledge of programming languages, database management, and software development methodologies.
    • Communication Skills: Effective verbal and written communication with both technical and non-technical stakeholders.
    • Interpersonal Skills: Collaboration with diverse teams and building relationships with stakeholders.
    • Problem-Solving Skills: Identify issues and develop effective solutions.
    • Project Management: Understanding of project management principles to manage timelines, resources, and deliverables.
    • Attention to Detail: Meticulousness in documenting requirements and specifications.
    • Adaptability: Willingness to learn new technologies and adapt to changing business needs.
    • Business Acumen: Understanding of the business domain and industry to align technical solutions with business goals.

    System Designer

    • Roles of a System Designer:

      • System Architecture Design: Define the overall structure, ensuring components work together.
      • Detailed Design Specifications: Create documents outlining how each component functions.
      • Integration Planning: Plan how components will interact with existing systems.
      • User Interface Design: Design user-friendly interfaces.
      • Database Design: Develop the database schema and data models.
      • Prototyping: Create prototypes to visualize design concepts.
      • Collaboration with Developers: Work closely with developers to ensure the system is built according to specifications.
      • Documentation: Maintain comprehensive design documentation.
      • Performance Optimization: Analyze system performance and make adjustments to improve efficiency, scalability, and reliability.
    • Required Skills of a System Designer:

      • Technical Proficiency: Strong knowledge of programming languages, software development frameworks, and database management systems.
      • Design Skills: Proficiency in design methodologies and tools, including UML.
      • Analytical Skills: Ability to analyze complex systems and identify design solutions that meet requirements.
      • Problem-Solving Skills: Capability to troubleshoot design issues and develop effective solutions.
      • Communication Skills: Strong verbal and written communication skills to convey design concepts and specifications.
