Transactions

• Transactions
• Basic business operations such as customer
  orders, purchase orders, receipts, time cards,
  invoices, and payroll checks in an organization
• Transaction processing systems (TPS)
• Perform routine operations and serve as a
  foundation for other systems

Batch vs. On-Line Transaction Processing

• Two types of TPS
• Batch processing
• A system whereby business transactions are
  accumulated over a period of time and prepared
  for processing as a single unit or batch
• On-line transaction processing (OLTP)
• A system whereby each transaction is processed
  immediately, without the delay of accumulating
  transactions into a batch
