Principles of Transaction Processing for the Systems Professional explains that this and many other computerized tasks require the use of transaction processing (TP). Authors Philip Bernstein and Eric Newcomer indicated that this area before specific design system will be more important with the growth of Internet commerce. (The so-called "ACID" test requires that the transaction will be atomistic, consistent, isolated, and durable.) The authors describe the principles with real world examples of transactions in everyday life, such as ATM systems and the stock market. Bernstein and Newcomer then explain how the transaction processing monitor the work and discuss some details, such as interface definition language, which allows computers to communicate a different, and procedures for long distance calls. This text also explores some real-world TP monitor products, from Cics IBM to Tuxedo to Microsoft Transaction Server. While transaction processing has become part of the design of mainframe systems for decades, it has recently become relevant to trade and access databases on the Web daily.
