MIS,UniversityofEducation,OkaraCampus 2 Transactions • Transactions… • Basic business operations such as customer orders, purchase orders, receipts, time cards, invoices, and payroll checks in an organization • A business activity between seller and buy to exchange an asset for payment. • Transaction processing systems (TPS) • A computerized system that performs and records the daily routine transactions necessary to the conduct of the business • Perform routine operations and serve as a foundation for other systems • A Transaction MIS (at operational level) • Question: a person using ATM machine is an example of TPS?

MIS,UniversityofEducation,Okara Campus 3 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 • Manufacturing products, supply chain, salaries • On-line transaction processing (OLTP) • A system whereby each transaction is processed immediately, without the delay of accumulating transactions into a batch • Real-time transaction • Mostly in Online shopping • Uses PCI cards(Payment Card Industry: MasterCard, Visa, Maestro, American Express, Discover, ) • Paypal or WorldPay, WePay, eWay, ICEPAY,

Characteristics of TPS • Performance • Rapid Processing : customers can’t wait for TPS to respond. • Reliability: Breakdown will disrupt or stop business • E.g.Banking, Financial, Stocks, Airline reservations • Consistency: All parties must agree on facts of exchange • Atomicity: All operations fail or succeed • Data Integrity • TPS is primarily concerned with data integrity • Efficiency • Paperless Transactions • Reduce manual data entry (errors) • Speed up transaction process • Elimination of redundant steps MIS,UniversityofEducation,OkaraCampus 9

Objectives of TPS MIS,UniversityofEducation,OkaraCampus 10 • Ensure data and information integrity and accuracy • Produce timely documents and reports • Increase labor efficiency • Help provide increased and enhanced service • Help build and maintain customer loyalty • Achieve competitive advantage

Processing Cycle Data Entry • Collecting and capturing transactions • No longer manual: • Old technologies Bar Codes, Magnetic Strips (credit cards) • New technologies RFID, Smart Cards, MIS,UniversityofEducation,OkaraCampus 11

Corporate databases of internal data Databases of external data Databases of valid transactions Operational Databases (CRM) Transaction processing systems MIS Decision support systems Executive support systems Expert systems Business transactions Input and error list Drill-down reports Exception reports Demand reports Key-indicator reports Scheduled reports Employees Corporate intranet Application databases UniversityofEducationOkaraCampus 12 App databases Ebay.com, photo.net uses Oracle Facebook.com built over MySQL Schematic View (Cont.)

Processing Cycle Database Maintenance • TPS helps ensure the databases are up-to-date and correct. • Multiple databases (internal & external) • A single purchase • decreases quantity – Inventory Database • decrease credit – Credit Card Database • increase sales – Sales Database MIS,UniversityofEducation,OkaraCampus 13

Processing Cycle Document/Report Generation • Examples • purchase orders • pay checks • sales receipts • invoices • bank statements An MIS also generates reports, but TPS reports are operational (no analysis). MIS,UniversityofEducation,OkaraCampus 14

Processing Cycle Inquiry Processing • Examples • when was a purchase made • does a customer have any credits on their account • was an item scheduled for delivery • was a package signed for An MIS also allows for inquiries, but the information available is summarized (or aggregated), i.e., What are the total sales for a whole department? What is the best selling product? MIS,UniversityofEducation,OkaraCampus 15

Processing Cycle MIS,UniversityofEducation,OkaraCampus 16

Transaction Processing System • An Order Entry System affects • accounting data • inventory data • customer data • financial data • invoicing data • Enhanced Feedback: • Inventory is updated at the point of ordering, not at the point of fulfillment. Eliminates surprise backorders (out-of-stock products). MIS,UniversityofEducation,OkaraCampus 17
