E COMMERCEUnit- I1. Introduction: It is a general concept covering any form of business transaction or information exchangeexecuted using information and communication technologies (ICT’s) It includes electronic trading of goods, services and electronic material. It takes place between companies, between companies and their customers, or betweencompanies and public administrations.They can be classified by application type:1. Electronic Markets Present a range of offerings available in a market segment so that the purchaser cancompare the prices of the offerings and make a purchase decision.Example: Airline Booking System2. Electronic Data Interchange (EDI) It provides a standardized system Coding trade transactions Communicated from one computer to another without the need for printed orders andinvoices & delays & errors in paper handling It is used by organizations that a make a large no. of regular transactionsExample: EDI is used in the large market chains for transactions with their suppliers3. Internet Commerce It is use to advertise & make sales of wide range of goods & services. This application is for both business to business & business to consumer transactions.Example: The purchase of goods that are then delivered by post or the booking of ticketsthat can be picked up by the clients when they arrive at the event2. Scope of E-Commerce: Internet e-commerce is one part of the overall sphere of e-commerce.SCCE CSEPage 3

E COMMERCE3. Electronic Commerce and the trade cycle: It can be applied to all, or to different phases of the trade cycle The trade cycle various depending on The nature of the organizations Frequency of trade between the patterns to the exchange The nature of goods and services being exchanged Trade cycle support1. Finding goods and services (referred to as a search & negotiation)2. Placing the order, taking delivery & making payment (execution and settlement)3. After sales activities such as warrantee, services etc.The three generic trade cycles can be identified:1. Regular, repeat transactions (repeat trade cycle)2. Irregular transactions, where execution & settlement are separated (credit transactions)3. Irregular transactions where execution & settlement are combined (cash transactions)SCCE CSEPage 4

E COMMERCEElectronic Markets: It increases the efficiency of the market It reduces the search cost for the buyer & makes it more likely that buyer will continuethe search until the best buy is found It exist in commodity, financial markets & they are also used in airline booking system It is irregular transaction tradecycle.Electronic Data Interchange: Applications are sending test results from the pathology laboratory to the hospital ordispatching exam results from exam boards to school It is used trade exchanges Users are vehicle assemblers, ordering components for the supermarkets It is used for regular repeat transactions It takes quite lot of work to set up systems It is part of schemes for just-in-manufacture and quick response supply Mature use of EDI allows for a change in the nature of the product or service Mass Customization is such an exampleSCCE CSEPage 5

E COMMERCEInternet Commerce: The first stage Advertising appropriate goods and services Internet sites offer only information & any further steps down the trade cycle areconducted on the telephone The Second stage An increasing no. of sites offer facilities to execute & settle the transaction Delivery may be electronic or by home delivery depending on the goods and services The final stage After-sales service On-line support & On-Line services.SCCE CSEPage 6

Anatomy of E-Commerce applicationsE-Commerce applications are:1. Multimedia Content for E-Commerce Applications2. Multimedia Storage Servers & E-Commerce Applicationsi. Client-Server Architecture in Electronic Commerceii. Internal Processes of Multimedia Serversiii. Video Servers & E-Commerce3. Information Delivery/Transport & E-Commerce Applications4. Consumer Access DevicesSCCE CSEPage 8

E COMMERCEMultimedia Content for E-Commerce Applications Multimedia content can be considered both fuel and traffic for electronic commerceapplications. The technical definition of multimedia is the use of digital data in more than one format,such as the combination of text, audio, video, images, graphics, numerical data,holograms, and animations in a computer file/document. Multimedia is associated with Hardware components in different networks. The Accessing of multimedia content depends on the hardware capabilities of thecustomer.Multimedia Storage Servers & E-Commerce Applications: E-Commerce requires robust servers to store and distribute large amounts of digitalcontent to consumers. These Multimedia storage servers are large information warehouses capable of handlingvarious content, ranging from books, newspapers, advertisement catalogs, movies,games, & X-ray images. These servers, deriving their name because they serve information upon request, musthandle large-scale distribution, guarantee security, & complete reliabilityi. Client-Server Architecture in Electronic Commerce All e-commerce applications follow the client-server modelSCCE CSEPage 9

E COMMERCE Clients are devices plus software that request information from servers or interact knownas message passing Mainframe computing , which meant for “dump” The client server model, allows client to interact with server through request-replysequence governed by a paradigm known as message passing. The server manages application tasks, storage & security & provides scalability-ability toadd more clients and client devices (like Personal digital assistants to Pc’s. See in fig.ii. Internal Processes of Multimedia Servers The internal processes involved in the storage, retrieval & management of multimediadata objects are integral to e-commerce applications. A multimedia server is a hardware & software combination that converts raw data intousable information & then dishes out. It captures, processes, manages, & delivers text, images, audio & video. It must do to handle thousands of simultaneous users. Include high-end symmetric multiprocessors, clustered architecture, and massive parallelsystems.iii. Video Servers & E-CommerceThe electronic commerce applications related to digital video will include1. Telecommunicating and video conferencing2. Geographical information systems that require storage & navigation over maps3. Corporate multimedia servers4. Postproduction studios5. Shopping kiosks.SCCE CSEPage 10

E COMMERCE Consumer applications will include video-on-demand. The figure which is of video–on demand consist video servers, is an link between thecontent providers (media) & transport providers (cable operators)Information Delivery/Transport & E-Commerce Applications Transport providers are principally telecommunications, cable, & wireless industries.Transport RoutersInformation Transport ProvidersInformation Delivery Methods Telecommunication companieslong-distance telephone lines; local telephone lines Cable television companiesCable TV coaxial, fiber optic & satellite lines Computer-based on-line serversInternet; commercial on-line service providers Wireless communicationsCellular & radio networks; paging systemsConsumer Access DevicesInformation ConsumersAccess Devices Computers with audio & videoMobile computingPersonal/desktop computing capabilities Telephonic devices Consumer electronics Personal digital assistants (PDAs)SCCE CSEVideophoneTelevision set-top box Game systemsPen-based computing, voice-driven computingPage 11

E COMMERCEE-Commerce Consumer applications: People needs entertainment on demand including video, games, news on-demand,electronic retailing via catalogs etc. Currently now we are taking the video on-demand. Why most companies betting heavily on this?1. 93 million homes have television2. Americans spend nearly half their free time watching television3. Every evening, more than one-third of the population is in front of a television4. Sight, sound, and motion combine to make television a powerful means of marketing1. Consumer Applications and Social Interaction: Lessons from history indicate that the most successful technologies are those that maketheir mark social In 1945, in U.S no one had TV. By 1960 about 86percent of households did Now contrast with Telephone. Bell invented the telephone in 1876 and by1940, 40% ofU.S. households and by 1980 about 95-98 percent of households connected Penetration was slower for Telephone than for TV because of the effort needed to set upthe wiring infrastructure The impact of both was good on business, social, consumer behavior and entertainmenthabits Radio began in 1960, and by 1989, almost 3 decades later, just 319 radio stationsfollowed the news format In 1994, their number exceeded 1000What do Consumers really want?1. They want quality and cost of service2. If a new system requires more steps to do essentially the same things, consumers mayresist it3. Some people fit that mold, but most of public prefers to lay back and just watchtelevision and let someone else do the work of figuring out the sequence of televisionprogrammingSCCE CSEPage 12

E COMMERCEWhat are Consumers willing to spend?1. According to the video on-demand, consumers get the cable bill at basic charge they willbuy2. If it is doubled they will not buy and at the service provider economics will increasedthen network operators might look to advertises to fill the gapDelivering products to Consumers1. Packing and distribution must be considered2. Blockbuster video collects the information and shows the typical consumer3. Spends 12 a month on home video expenditures4. Go to video store to select video on limited budget and has time to kill5. Only periodically expends a large sum of moneyConsumer Research and E-CommerceConsumer opinion about interactive television is 46% be willing to pay 39% want video phone calls 63% would pay for movies on-demand 57% would pay for Television shows on-demand 78% said their worry about it is that they will pay for something that they previouslyreceived free of charge 64% are think it make it harder for viewers to protect privacy 41% are tell that it is too confusing to useChanging business Environment1. The traditional business environment is changing rapidly2. Many companies are looking outside and within to shape business strategies3. uppliers,distributors,industry groups etcconnectionsto4. The I-superhighway will expand this trend so that it allow business to exchangeinformation.SCCE CSEPage 13

E COMMERCEE-Commerce and the retail Industry1. Conditions are changing in the “new economy” with respect to the retail industry2. Consumers are demanding lower prices, better quality, a large selection of in-seasongoods.3. Retailers are filling their order by slashing back-office costs, reducing profit margins,reducing cycle times. buying more wisely and making huge investments in technology4. Retailers are in the immediate line of fire and were first to bear the brunt of cost cuttingMarketing and E-Commerce1. E-commerce is forcing companies to rethink the existing ways of doing target marketingand even event marketing.2. Interactive marketing is in electronic markets via interactive multimedia catalogs3. Users find moving images more appealing than still image and listening more appealingthan reading text on a screen4. Consumer information services are a new type of catalog businessInventory Management and Organizational Applications1. With borders opening up and companies facing stiff global competition2. Adaptation would include moving to computerized, “paperless” operations to reduce3. Once targeted business process is inventory management, solutions for these processes goby different names4. In manufacturing industry they’re known as just-in-time inventory systems, in the retailas quick response programs, and in transportation industry as consignment trackingsystemsSCCE CSEPage 14

E COMMERCEJust-in-Time (JIT) Manufacturing1. It is viewed as an integrated management system consisting of a number of differentmanagement practices dependent on the characteristics of specific plants2. The first principle is elimination of all waste (time,materials,labour & equipment)3. The following management practices are focused factory, reduced set-up times, grouptechnology, total productive maintenance, multifunction employees, uniform workloads,IT purchasing,kanban total quality control & quality circlesQuick Response Retailing (QR)1. It is a version of JIT purchasing tailored for retailing2. To reduce the risk of being of out of stock, retailers are implementing QR systems3. It provides for a flexible response to product ordering and lowers costly inventory levels4. QR retailing focuses on market responsiveness while maintaining low levels of stocks5. It creates a closed loop consisting of retailer, vendor, & consumer chain,& as consumersmake purchases the vendor orders new deliveries from the retailer through its computernetworkSupply Chain Management1. QR and JIT address only part of the overall picture2. Supply Chain Management (SCM) is also called “extending”, which means integratingthe internal and external partners on the supply and process chains to get raw materials tothe manufacturer and finished products to the consumer3. It includes following functions Supplier management: The goal is to reduce the number of suppliers and get them topartnersSCCE CSEPage 15

E COMMERCE Inventory management: The goal is to shorten the order-ship-bill cycle. When a majorityof partners are electronically linked, information faxed or mailed Distribution management: The goal is to move documents (accurate data) related toshipping Channel management: The goal is to quickly disseminate information about changingoperational conditions ( technical, product, and pricing information) to trading partners Payment management: The goal is to link company and the suppliers and distributors sothat payments can be sent and received electronically Financial management: The goal is to enable global companies to manage their money invarious foreign exchange accounts Sales force productivity: The goal is to improve the communication flow of informationamong the sales, customer & production functionsIn sum, the supply chain management process increasingly depends on electronic marketsWork group Collaboration Applications:1. A internetwork that enables easy and inexpensive connection of various organizationalsegments2. It is to improve communications and information sharing and to gather and analyzecompetitive data in real-time3. Videoconferencing, document sharing and multimedia e-mail, are expected to reducetravel and encourage telecommuting4. Improves the distribution channel for documents and records to suppliers, collaboratorsand distributorsSCCE CSEPage 16

Personal Finance and Home Banking Management: The newest technologies are direct deposit of payroll, on-line bill payment and telephonetransfers The technology for paying bills, whether by computer or telephone, is infinitely moresophisticated than anything on the market a few years ago In 1980s were the days of “stone age” technology because of technology choices foraccessing services were limited For home banking, greater demands on consumers and expanding need for information,it’s services are often categorized as basic, intermediate and advanced(i) Basic services These are related to personal finance The evolution of ATM machines from live tellers and now to home banking The ATM network has with banks and their associations being the routers and the ATMmachines being the heterogeneous computers on the network. This interoperable network of ATMs has created an interface between customer and bankthat changed the competitive dynamics of the industry. See in next figure Increased ATM usage and decrease in teller transactions The future of home banking lies with PC’sSCCE CSEPage 18

E COMMERCE(ii) Intermediate Services The problem with home banking in 1980 is, it is expensive service that requires a PC, amodem and special software As the equipment becomes less expensive and as bank offers broader services, homebanking develop into a comprehensive package that could even include as insuranceentertainment Consider the computerized on-line bill-payment system It never forgets to record a payment and keeps track of user account number, name,amount and the date and we used to instruct with payment instructions. See in Fig;(iii)Advanced Services The goal of advanced series is to offer their on-line customers a complete portfolio oflife, home, and auto insurance along with mutual funds, pension plans, home financing,and other financial products The Figure explains the range of services that may well be offered by banks in future The servic3es range from on-line shopping to real-time financial information fromanywhere in the world In short, home banking allows consumers to avoid long lines and gives flexibilitySCCE CSEPage 19

E COMMERCE2. Home Shopping: It is already in wide use. This enable a customer to do online shopping(i) Television-Based Shopping: It is launched in 1977 by the Home Shopping Network (HSN). It provides a variety of goods ranging from collectibles, clothing, small electronics, housewares, jewelry, and computers.

At this time, cable shopping channels are not truly interactive(ii) Catalog-Based Shopping In this the customer identifies the various catalogs that fit certain parameters such assafety, price, and quality The on-line catalog business consists of brochures , CD-ROM catalogs, and on-lineinteractive catalogs Currently, we are using the electronic brochuresSCCE CSEPage 20

E COMMERCE3. Home Entertainment: It is another application for e-commerce Customer can watch movie, play games, on-screen catalogs, such as TV guide. In Home entertainment area, customer is the control over programming In Table tells the, What will be required in terms of Television-based technology for thistelemart to become a realityThe Telemart: Present and Future Functions Compressing and decodingThe transition to digital satellitea digital signal(images areand cable network head broadcompress to reduce quantitycasting involves linking the TVof information)to decoder to reconvert into ananalog signal Decoding a scrambledsignalThe broad casting of pay channelrequires the encryption of thesignal on emission & unscrambled Rapid loading of programon memoryAn increase in the no. of individualinteractive services is possibleonly if n/w overloading is keptminimum Electronic money orcard payment terminalOnce separated from the telephone,telemart will need a keyboardup to the TV set in order to ensureinteractivity.
