7. TYPES OF TRANSACTION PROCESSING SYSTEMS • Batch Transaction Processing • Examples:- • Cheque Clearance • Bill Generation • Credit Card Transactions

8. REAL-TIME TRANSACTION PROCESSING • Main disadvantage of RTTP is the hardware and software costs exceed batch. • Two main concerns:- • Concurrency • Atomicity • Examples of RTTP :- • Reservation Systems • Pos Terminals • Library Loan System
