Transaction processing systems
• Data entry

• Inquiry processing
TPS: Data Entry
• Traditional method: manual data entry
• Source data automation– Point of Sale (POS) terminals & ATMs– Bar codes, credit card magnetic stripes, etc.– Prerecording frequently seen data (autofill)
TPS: Batch vs. Real-Time Processing
• Batch processing– Good for applications that are utilized at scheduled
intervals– Ex: customer statements
• Real-time processing– Online transaction processing (OLTP)– Immediate updating of databases & inquiries– Required: access to databases at anytime– Fault-Tolerant systems (“Fault-proofed”)
• Redundant processors, storage facilities
TPS: Document & Report Generation
• Action documents– Purchase orders
• Information documents– Receipts– Customer statements
