3An Introduction to Electronic Commerce
- Electronic commerce conducting business
activities (e.g., distribution, buying, selling,
marketing, and servicing of products or services)
electronically over computer networks such as the
Internet, extranets, and corporate networks - Business activities that are strong candidates
for conversion to e-commerce - Paper-based
- Time-consuming
- Inconvenient for customers
4Business-to-Business (B2B)
E-Commerce
- Business-to-business (B2B) e-commerce subset of
e-commerce where all the participants are
organizations - Considerably larger and growing more rapidly than
the business-to-consumer market
5Business-to-Consumer (B2C) E-Commerce
- Business-to-consumer (B2C) e-commerce customers
deal directly with the organization, avoiding any
intermediaries - Elimination of intermediaries
- Squeezes costs and inefficiencies out of supply
chain - Can lead to higher profits for companies and
lower prices for consumers
6Consumer-to-Consumer (C2C) E-Commerce
- Consumer-to-consumer (C2C) e-commerce
participants are individuals, with one serving as
the buyer and the other as the seller - eBay example of a C2C e-commerce site
7eGovernment
- eGovernment use of information and
communications technology to simplify the sharing
of information, speed formerly paper-based
processes, and improve the relationship between
citizen and government - Forms of eGovernment

maturing much later than in Western Europe and
Japan - Western European and Japanese consumers are much
more willing to use m-commerce - Mobile phone gaming in the United States is
expected to increase from about 380 million in
2006 to more than 1 billion by 2009
10Technology Needed for Mobile Commerce
- Handheld devices used for m-commerce have
limitations that complicate their use - Wireless application protocol (WAP) a standard
set of specifications for Internet applications
that run on handheld, wireless devices
11Electronic and Mobile CommerceApplications
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
12Manufacturing
- 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
13Manufacturing (continued)

Systems in Perspective
30Traditional 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
31Traditional Transaction Processing Methods and
Objectives (continued)
Figure 5.6 Batch Versus Online Transaction
Processing
32Transaction Processing Activities
- TPSs
- Capture and process data that describes
fundamental business transactions - Update databases

collection, data editing, data correction, data
manipulation, data storage, and document
production
33Transaction Processing Activities (continued)
Figure 5.8 Data-Processing Activities Common to
Transaction Processing Systems
34Data Collection
- Data collection capturing and gathering all data
necessary to complete the processing of
transactions - Data should be
- Collected at source
- Recorded accurately and in a timely fashion
35Data Editing
- Data editing the process of checking data for
validity and completeness - Example quantity and cost data must be numeric
and names must be alphabetic otherwise, the data
is not valid
36Data Correction
- Data correction the process of reentering data
that was not typed or scanned properly - Example a scanned UPC code must match a code in
a master table of valid UPCs
37Data Manipulation
- Data manipulation the process of performing
calculations and other data transformations
related to business transactions - Includes classifying data, sorting data into
categories, performing calculations, summarizing
results, and storing data in the organizations
database for further processing
38Data Storage
- Data storage the process of updating one or more
databases with new transactions - After being updated, this data can be further
processed and manipulated by other systems and
made available for management reporting and
decision making
39Document Production and Reports
- Document production the process of generating
output records and reports - Hard-copy paper reports
- Displays on computer screens (soft copy)
40Control and Management Issues Disaster Recovery

describing the actions that must be taken to
restore computer operations and services in the
event of a disaster - Necessary for preventing a lengthy disruption in
the operation of any of a companys critical
business information systems that directly affect
its cash flow
41Transaction Processing System Audit
- Transaction processing system audit a check of a
firms TPS systems to prevent accounting
irregularities and/or loss of data privacy - Attempts to answer four basic questions
- Does the system meet the business need for which
it was implemented? - What procedures and controls have been
established? - Are these procedures and controls being used
properly? - Are the information systems and procedures
producing accurate and honest reports?

Figure 5.11 Enterprise Resource Planning System
48An Overview of Enterprise Resource Planning
- ERP systems evolved from materials requirement
planning systems (MRP) developed in the 1970s - 1980s - early 1990s organizations recognized
that their legacy transaction processing systems
lacked integration - Result higher costs and poorer customer service

55Financial and Managerial Accounting (continued)
- In an ERP system, input to the general ledger
occurs simultaneously with the input of a
business transaction - Financial accounting capturing and recording all
transactions that affect a companys financial
state and using these documented transactions to
prepare financial statements to external decision
makers, such as stockholders, suppliers, banks,
and government agencies
56Financial and Managerial Accounting (continued)
- Managerial accounting use of historical and
estimated data to provide information that
management uses in conducting daily operations,
in planning future operations, and in developing
overall business strategies
57Hosted Software Model for Enterprise Software
- Target market small-to-medium businesses
- Offered by vendors such as NetSuite,
Salesforce.Com Inc., Everest Software, and SAP - Appealing to small businesses because they
