E-Commerce Applications: Retail and Wholesale

• Electronic retailing (e-tailing): the direct sale from business to consumer through electronic storefronts, typically designed around an electronic catalog and shopping cart model

• Cybermall: a single Web site that offers many products and services at one Internet location

• Manufacturing, repair, and operations (MRO) goods and services


Manufacturing

• To raise profitability and improve customer service, many manufacturers move their supply chain operations onto the Internet

• Electronic exchange: an electronic forum where manufacturers, suppliers, and competitors buy and sell goods, trade market information, and run back-office operations


Manufacturing (continued)

Figure 5.3: Model of an Electronic Exchange


Marketing

• Market segmentation: the identification of specific markets to target them with advertising messages

An Overview of Transaction Processing Systems (continued)

Figure 5.6: TPS, MIS/DSS, and Special Information Systems in Perspective


Traditional Transaction Processing Methods and Objectives

• Batch processing system: method of computerized processing in which business transactions are accumulated over a period of time and prepared for processing as a single unit or batch

• Online transaction processing (OLTP): computerized processing in which each transaction is processed immediately, without the delay of accumulating transactions into a batch


Traditional Transaction Processing Methods and Objectives (continued)

Figure 5.7: Batch Versus Online Transaction Processing


Transaction Processing Activities

• TPSs– Capture and process data that describes fundamental

business transactions– Update databases– Produce a variety of reports

• Transaction processing cycle: the process of data collection, data editing, data correction, data manipulation, data storage, and document production
