Chapter 6 Flashcards
is the use of the Internet and other networks and information technologies to
support e-commerce, enterprise communications and collaboration, and Web-enabled
business processes, both within a networked enterprise and with its customers and
business partners.
e-Business
includes e-commerce, which involves the buying and selling and marketing
and servicing of products, services, and information over the Internet and other networks.
E-business
Many companies today are using information technology to develop ___________ that cross the boundaries of traditional business functions in order to reengineer and improve vital business processes all across the enterprise.
integrated cross-functional enterprise systems
These organizations view cross-functional enterprise systems as a strategic way to use IT to share information resources and improve the efficiency and effectiveness of business processes, and develop strategic relationships with customers, suppliers, and business
partners.
Cross-Functional Enterprise Applications
Companies first moved from ___________ to integrated
cross-functional client/server applications. This typically involved installing enterprise resource planning, supply chain management, or customer relationship management
software from SAP America, PeopleSoft, Oracle, and others.
functional mainframe-based legacy systems
Instead of focusing on the information processing requirements of business functions, such enterprise software focuses on supporting integrated clusters of business processes involved in the operations of a business.
Cross-Functional Enterprise Applications
Companies are using the ______ and ____________ as a technology platform for their cross-functional and inter enterprise information systems.
World Wide Web
their intranets and extranets
an _________, which illustrates the
interrelationships of the major cross-functional enterprise applications that many companies have or are installing today.
enterprise application architecture
It provides a conceptual framework to help us visualize the basic components, processes, and interfaces of these major e-business applications, and their interrelationships to each other.
Enterprise application architecture
This____ also spotlights the roles these business systems play in supporting the customers, suppliers, partners, and employees of a business
application architecture
concentrates on the efficiency of a firm’s internal production, distribution, and financial processes.
enterprise resource planning (ERP)
focuses on acquiring and retaining profitable customers via marketing, sales, and service processes.
Customer relationship management (CRM)
aims to acquire and retain partners who can enhance the sale and distribution of a firm’s products and services.
Partner relationship management (PRM)
focuses on developing the most efficient and effective sourcing and procurement processes with suppliers for the products and services that a business needs.
Supply chain management (SCM)
applications provide a firm’s employees with tools that support group collaboration and decision support.
Knowledge management (KM)
software is being used by many companies to connect their major e-business applications.
Enterprise application integration (EAI) software
enables users to model the business processes involved in the interactions
that should occur between business applications
EAI software
also provides middleware that performs data conversion and coordination, application communication and messaging services, and access to the application interfaces involved.
EAI
can integrate a variety of enterprise application clusters by letting them exchange data according to rules derived from the business process models developed by users.
EAI software
can integrate the front-office and back-office applications of a business so
they work together in a seamless, integrated way.
EAI software
This is a vital capability that provides real business value to a business enterprise that
must respond quickly and effectively to business events and customer demands.
- For example, the integration of enterprise application clusters has been shown to
dramatically improve customer call center responsiveness and effectiveness.
EAI software
integrates access to all of the customer and product data that
customer representatives need to quickly serve customers.
EAI
also streamlines sales order processing so products and services can be delivered
faster
EAI
improves customer and supplier experience with the business because of its
responsiveness.
EAI
are cross-functional information systems that process data resulting from the occurrence of business transactions
Transaction processing systems (TPS)
are events that occur as part of doing business, such as sales, purchases, deposits, withdrawals, refunds, and payments.
Transactions
Data about the customer, product, salesperson, store, and so on, must be captured and processed
Transaction Processing Systems
This need prompts additional transactions, such as credit checks, customer billing, inventory changes, and increases in accounts receivable balances, which generate even more data.
Transaction Processing Systems
are needed to capture and process such data, or the operations of a business would grind to a halt
transaction processing activities
play a vital role in supporting the operations of most companies today
transaction processing systems
play a strategic role in Web-enabled businesses
Online transaction processing systems
Many firms are using the Internet and other networks that tie them electronically to their
customers or suppliers for
___________
online transaction processing (OLTP)
Such real-time systems, which capture and process transactions immediately, can help
firms provide superior service to customers and other trading partners.
- This capability adds value to their products and services, and thus gives them an important
way to differentiate themselves from their competitors.
Transaction Processing Systems
use a five cycle of data entry, transaction processing, database maintenance, document and report generation, and inquiry processing activities
transaction processing cycle
The first step of the transaction processing cycle is the capture of business data.
- For example, transaction data may be collected by point-of-sale terminals using optical scanning of bar codes and credit card readers at a retail store or other business.
- Transaction data can also be captured at an e-commerce Web site on the Internet.
- The proper recording and editing of data so they are quickly and correctly captured for processing is one of the major design challenges of information systems.
Data Entry
Transaction processing systems process data in two basic ways:
Batch processing
real-time processing
, where transaction data are accumulated over a period of time
and processed periodically
batch processing
(also called online processing), where data are processed
immediately after a transaction occurs.
real-time processing
All ____________ incorporate real-time processing capabilities
online transaction processing systems
Many online systems also depend on the capabilities of __________ computer systems that can continue to operate even if parts of the system fail.
fault tolerant
- An organization’s databases must be updated by its transaction processing systems so that they are always correct and up-to-date.
- Therefore, transaction processing systems serve to assist in maintaining the corporate databases of an organization to reflect changes resulting from day-to-day business transactions.
- For example, credit sales made to customers will cause customer account balances to be
increased and the amount of inventory on hand to be decreased. - Database maintenance ensures that these and other changes are reflected in the data records stored in the company’s databases.
Database Maintenance
- Transaction processing systems produce a variety of documents and reports.
- Examples of transaction documents include purchase orders, paychecks, sales receipts, invoices, and customer statements.
- Transaction reports might take the form of a transaction listing such as a payroll register, or edit reports that describe errors detected during processing.
Document and Report Generation
- Many transaction processing systems allow us to use the Internet, intranets, extranets, and Web browsers or database management query languages to make inquiries and receive responses concerning the results of transaction processing activity.
- Typically, responses are displayed in a variety of prespecified formats or screens.
- For example, one might check on the status of a sales order, the balance in an account, or the amount of stock in inventory and receive immediate responses at your PC.
Inquiry Processing
are cross-functional information systems that enhance communication, coordination, and collaboration among the members of business teams and workgroups.
Enterprise collaboration systems (ECS)
The goal of enterprise collaboration systems is to enable us to work together more easily
and effectively by helping us to:
communicate
coordinate
collaborate
Share information with each other.
Communicate
