OLTP: Online Transaction Processing
Online Transaction Processing (or OLTP) is a class of program that facilitates and manages transaction-oriented applications, typically for data entry and retrieval transaction processing. OLTP also refers to computer processing in which the computer responds immediately to users' requests. An automatic teller machine for a bank is an example of transaction processing. Probably the most widely installed OLTP product is IBM's CICS (Customer Information Control System).
