- 4. OVERVIEW OF TPS • TRANSACTION PROCESSING SYSTEMS ARE CRUCIAL TO THE OPERATION OF MOST FINANCE, BANKING AND ELECTRONIC COMMERCE ORGANIZATIONS. • TRANSACTION PROCESSING IS PRIMARILY CONCERNED WITH MAINTAINING DATA INTEGRITY. • SUCH SYSTEMS CAN OPERATE AT THE SINGLE DATABASE LEVEL, BUT THEY ALSO OPERATE AT HIGHER LEVELS WHERE DATA IN MANY DATABASES AND EVEN MANY DIFFERENT SYSTEMS IS INVOLVED. FOR EXAMPLE TRANSFERRING FUNDS FROM ONE FINANCIAL INSTITUTION TO ANOTHER.
- 5. EXAMPLES OF TPS • ATM MACHINES • PAYROLL SOFTWARE • RESERVATION SYSTEMS • POINT OF SALE TERMINAL • LIBRARY LOAN SYSTEMS • BILL GENERATION • CREDIT CARD SALE TRANSACTIONS

THE CONCEPT TPS • A TRANSACTION PROCESSING SYSTEM (TPS) IS A TYPE OF INFORMATION SYSTEM THAT COLLECTS, STORES, MODIFIES AND RETRIEVES THE DATA TRANSACTIONS OF AN ENTERPRISE OR LARGE BUSINESS. • THE NEED TO HANDLE HUNDREDS, EVEN THOUSANDS OF SIMULTANEOUS USERS. PAYMENT PROCESSING AND RESERVATIONS • THE NEED TO ALLOW MANY USERS TO WORK ON THE SAME SET OF DATA, WITH IMMEDIATE UPDATING. ONLINE ORDERS • THE NEED TO HANDLE ERRORS IN A SAFE AND CONSISTENT MANNER.
- 7. PLACES THEY ARE USED • BANKS • ONLINE SHOPPING • GAS STATIONS • RETAIL SHOPPING • CAR DEALERS • LIBRARIES • AIR PORTS • ATM MACHINES
- 9. TYPES OF TPS BATCH TPS • TRANSACTIONS ARE ACCUMULATED OVER A PERIOD OF TIME AND PROCESSED AS A SINGLE UNIT. • BATCH SYSTEM, HIGH VOLUME OF DATA, SEPARATE INPUT AND OUTPUT SYSTEMS. • SOFTWARE USED TO SEND OUT PAYROLL AND BILLING STATEMENTS. • BANKS, HUMAN RESOURCE DEPARTMENTS AND STORES REAL TIME TPS • TRANSACTIONS ARE PROCESSED IMMEDIATELY AS THEY OCCUR FAMILY. • THEY PROCESS REAL TIME TRANSACTION IN A SINGLE TRANSACTION. • IN NEAR INSTANT TRANSACTION. • ATM MACHINES, RESERVATION SYSTEMS, LIBRARIES AND CUSTOMER SERVICE PORTALS.
- 10. BATCH TPS ADVANTAGES • REPEATED JOBS DONE QUICKLY • ABILITY TO WORK OFFLINE • CAN SCHEDULE WHEN TRANSACTIONS OCCUR • MULTIPLE USERS DISADVANTAGES • COMPUTER OPERATORS MUST BE TRAINED • DIFFICULT TO DEBUG • COSTLY • ERRORS
- 11. REAL TIME TPS ADVANTAGES • MAXIMUM CONSUMPTION • TASK SHIFTING • ERROR FREE • 24-7 SYSTEM DISADVANTAGES • LIMITED TASKS • LOW MULTI TASKING • EXPENSIVE • DIFFICULT PROGRAMING REHMAN, 2012
- 12. TRANSACTION PROCESSING SYSTEM ADVANTAGES • ABILITY TO COMPETE • MULTIPLE TASK • GLOBALIZATION DISADVANTAGES • SECURITY ISSUES • DOWN TIME • OPERATION HANDLING
- 13. SOLUTIONS TO TPS PROBLEMS PASSWORDS AND PINS ENCRYPTION FIREWALLS UPDATE SYSTEMS PCI COMPLIANCE
- 14. QUALIFIERS ACID IS AN ACRONYM FOR ATOMICITY, CONSISTENCY, ISOLATION AND DURABILITY. THE AIM IS TO ENSURE ALL TRANSACTIONS COMPLY WITH THESE FOUR PROPERTIES. THEY ENSURE THAT: • TRANSACTIONS ARE NEVER INCOMPLETE (ATOMICITY), THE DATA IS NEVER INCONSISTENT. • (CONSISTENCY), TRANSACTIONS DO NOT INTRUDE OR AFFECT EACH OTHER (ISOLATION) • THE RESULTS OF A COMPLETED TRANSACTION ARE PERMANENT (DURABILITY). • ALL THESE PROPERTIES COMBINE TO ENSURE THE INTEGRITY OF ALL DATA IS MAINTAINED BEFORE, DURING AND AFTER EACH TRANSACTION
