    Study Notes

    Data Warehouses

    • Organized by subject, focusing on product types sold by retailers.
    • Individual product data (revenue, costs, warranty details) is consolidated into summary data for managerial reports.
    • Sources of data for warehouses include:
      • Internal sources: Sales, billing, inventory, customer databases, and ad hoc tools.
      • External sources: Data from vendors and suppliers, including product specs and shipment information.
      • Clickstream data: Captured from website user interactions, providing insights into user behavior, preferred pages, and demographics.

    Data Marts

    • Small components of data warehouses, allowing focused analysis on related data sets.
    • Tailored to specific business segments, facilitating easier access to relevant data.
    • Example: A data mart for sales-related information isolates data from unrelated customer service or shipping data.

    Data Mining

    • Techniques used for analyzing customer behavior to improve marketing strategies.
    • Enables businesses to identify customer types and purchasing motivations.
    • Different techniques yield various informational outputs for decision-making.

    Information Systems

    • Perform essential functions: acquiring data, processing it, storing, and providing outputs for user interpretation.
    • Types of information produced: operational, managerial, and strategic, tailored to organizational needs.
    • Systems vary based on the specific information required for management.

    Transaction-Processing System (TPS)

    • Operational-level systems that track daily business transactions (e.g., order tracking, payroll).
    • Supports real-time or batch processing:
      • Real-time processing: Captures data instantly as transactions occur.
      • Batch processing: Accumulates transactions for processing at a later point, suitable for non-time-sensitive activities.

    Management Information System (MIS)

    • An evolution of TPS, enhancing data organization and output utility.
    • Generates three report types:
      • Detail Report: Lists all transactions over a specific period.
      • Summary Report: Consolidates detailed data with visual aids like charts.
      • Exception Report: Highlights unusual conditions or items requiring attention.
