    Study Notes

    Transaction Processing System (TPS)

    • A transaction processing system (TPS) facilitates the capture, processing, storage, and retrieval of business transactions.
    • Examples of transactions include sales, purchases, payments, and operational activities.
    • Key components:
      • Transaction Capture: Collects data related to transactions, such as scanning barcodes at a checkout.
      • Transaction Processing: Processes transactions in real-time, ensuring accuracy and updating databases, like updating inventory after a sale.
      • Database: Stores transaction data in a centralized database (e.g., a database containing customer orders, product details, and transaction timestamps).
      • Output Generation: Generates outputs like receipts, reports, and updated records, supporting decision-making and accurate recordkeeping (e.g., printing a sales receipt).
      • Feedback: Provides feedback to users on transaction success or failure (e.g., displaying an error message if a transaction fails).

    TPS Characteristics

    • Real-time processing: Processes transactions immediately, ensuring up-to-date information and data integrity for operational decisions.
    • Reliability: Designed for high reliability and availability, ensuring continuous operation even in the face of failures or disruptions.
    • Data Integrity: Validates transactions before processing, ensuring accuracy and consistency of data.

    Batch Processing

    • Some TPS support batch processing, handling large transaction volumes during off-peak hours.

    TPS Applications
