Ch 5 - Electronic and Mobile Commerce and Enterprise Systems
- Electronic Commerce: conducting business activities electronically over computer networks
\
- Types of E-Commerce:
1. Business-to-business (B2B): all participants are organisations. It is a useful tool for connecting business partners in a virtual supply chain to cut resupply times and reduce costs 2. Business-to-Consumer (B2C): where customers deal directly with an organisation and avoid intermediaries 3. Consumer-to-Consumer (C2C): Involves consumers selling directly to other consumers. Example: craigslist, eBid, bidzcom
\
- Disintermediation: the elimination of intermediate organisations between the producer and the consumer

- E-Government: use of information and communications technology to: * Simply the sharing of information * Speed formerly paper-based processes * Improve the relationship between citizen and government
\
- Forms of E-Government:
1. Government-to-Consumer (G2C) 2. Government-to-Business (G2C) 3. Government-to-Government (G2G)
\
- Mobile-commerce (m-commerce) relies on the use of wireless devices * The Internet Corporation for Assigned Names and Numbers (ICANN): * Created a .mobi domain to attract mobile users to the web * M-commerce will succeed only if it provides users with real benefits * B2B, B2C, C2C, and m-commerce are used in: retail and wholesale, manufacturing, marketing and advertising, price comparison, couponing, investment and finance, banking and e-boutiques
\
- Electronic Retailing (e-tailing): * Direct sale from business to consumer through electronic storefronts
- Cybermall: * Single web site that offers many products and services at one internet location
- Manufacturing, repair, and operations (MRO): * Purchases often approach 40% of a manufacturing company’s total revenue
- Manufacturing: * Electronic exchange: electronic forum where manufacturers, suppliers, and competitors buy and sell goods, trade market information, and run back-office operations * Private exchange: owned and operated by a single company * Public exchanges: owned and operated by industry groups * Market segmentation: identification of specific markets to target them with advertising messages

\
- Advertising: * Mobile and impressions are generally bought at cost per thousand (CPM), cost per click (CPC), or cost per action (CPA) * Price comparison: mobile phones services enable shoppers to compare prices and products on the web * Couponing: shoppers can subscribe to mobile coupon aggregators
\
- Investment and Finance: * The Internet: revolutionised the world of investment and finance * The brokerage business: adapted to the internet faster than any other arm of finance * Online banking customers can check balances, transfer money, and pay their bills
- Hardware: * Key e-commerce infrastructure factor: web server hardware platform complete with the appropriate software * Key decision facing new e-commerce companies: to host their own web site or let someone else do it
\
- Each e-commerce website must have web server software to perform fundamental services: * Security and identification * Retrieval and sending of web pages * Web site tracking * Website development * Web page development * Difference between web page and web site is that a website is the entire site, whereas a web page is the first page of the web site * The E-Commerce Software should be able to manage the catalogue, configure products to help customers, have shopping cart facilities, e-commerce transaction processing, and web traffic data analysis
\
- M-Commerce Hardware and Software: For the m-commerce to work effectively, the interface between the wireless, handheld device and its user must improve * Encryption can provide secure transmission * Wireless Application Protocol (WAP): standard set of specifications for internet applications that run on handheld, wireless devices
\
- Electronic Payment Systems: * Digital certificate: attachment in a website that verifies the identity of a sender or website * Certificate authority (CA): trusted third party organisation that issues digital certificates * Secure sockets layer (SSL): used to secure sensitive data * Electronic cash: amount of money that is computerised for e-commerce transactions * Smart card: card sized device with a microchip for electronic memory and processing capability * P-card: credit card used to streamline the traditional purchase order and invoice payment process
\
- Transaction Processing Systems (TPS): * Can capture detailed data necessary to update records about fundamental business operations * Include order entry, inventory control, payroll account payable * Provide employees with data to help them achieve their goals
\
- Traditional transaction processing methods and objectives * Batch processing system: * Data processing of business transactions as they accumulate over a period of time and are prepared for processing as a single unit or batch * Online transaction processing (OLTP): * Data processing in which each transaction is processed immediately
\
- Transaction Processing System: an information processing system for business transactions involving the collection, modification and retrieval of all transaction data. * TPS captures and processes data that describes fundamental business transactions * Updates databases * Produces a variety of reports
- Transaction processing cycle: * The process of data collection, data editing, data correction, data manipulation, data storage, and document production
\ * Data Collection: * Capturing and gathering all data necessary to complete the processing of transactions

- Data collection should be collected at source, recorded accurately, in a timely fashion
- Data collection __could__be manual or automated via special input devices \n
- POS Transaction Processing System:

\
- Data Editing: checking data for validity and completeness to detect any problems * Examples: quantity and cost data must be numeric, names must be alphabetic
\
- Data Correction: reentering data that was not typed or scanned properly * Error messages must specify the problem so proper corrections can be made
\
- Data Manipulation: performing calculations and other data transformations related to business transactions * Can include: classifying data, sorting data into categories, performing calculations, summarising results, storing data in the organisation’s database for further processing
\
- Data Storage: updating one or more databases with new transactions * After being updated, this data can be further processed and manipulated by other systems
\
- Document Production and Reports: * Generating output records, documents, and reports * Hard-copy paper reports * Displays on computer screens * Results from one TPS can be inputs to another system
\
- A TPS usually includes the following types of systems: * Order processing systems * Accounting systems * Purchasing systems
\
- Enterprise Resource Planning: software used by a company to manage key parts of operations, including accounting and resource management
- ERP systems: * Central to the organisation * Ensure information can be shared across all business functions * Employ a database of key operational and planning data that can be shared by all

- ERP systems evolved from materials requirement planning system (MRP). Large organisations are the first to take on the challenge of implementing ERP
\
- Advantages of ERP: * Improved access to data for operational decision making * Elimination of costly, inflexible legacy systems * Improvement of work processes * Upgrade of technology infrastructure
\
- Disadvantages of ERP: * Expense and time in implementation * Difficulty implementing change * Difficulty integrating with other systems * Difficulty in loading data into new ERP system * Risks in using one vendor * Risk of implementation failure
\
- ERP for small and medium-size enterprises (SMEs): * Many SMEs elect to implement open-source ERP systems * Anyone can see and modify the source code to customise it to meet their needs with open-source software
\
- Supply Chain Management is the management of the flow of goods and services and includes all processes that transform raw materials into final products
- It includes: * Planning, executing, and controlling all activities involved in raw material sourcing and procurement * Converting raw materials to finished products and warehousing and delivering finished product to customers
\
- Process for developing a production plan: * Sales forecasting * Sales and operations plan (S&OP) * Demand management * Detailed scheduling * Materials requirement planning (MRP) * Purchasing * Production
\
- Financial and Managerial Accounting * General ledger: main accounting record of a business
\
- ERP system: * Captures transitions entered by workers in all function areas of a business * Creates associated general ledger record to track the financial impact of the transaction
\
- Hosted software model for enterprise software: means the small business firm does not need to employ a full-time IT person to maintain key business applications
\
- Advantages & Disadvantages: \n
* Challenges faced by multinational corporations when planning, building, and operating their TPSs:
* Dealing with different languages and cultures
* Disparities in IS infrastructure
* Varying laws and customs rules
* Multiple currencies
