Introduction to e-Business Systems
E-business is the use of the Internet and other networks and information technologies to support electronic commerce, enterprise communications and collaboration, and Web-enabled business processes, both within a networked and information technologies
E-business includes e-commerce It involves the buying and selling and
marketing and servicing of products, services, and information over the Internet and other networks

Cross-Functional Enterprise Applications
Many companies are using IT to develop integrated cross-functional enterprise systems that cross the boundaries of traditional business functions in order to reengineer and improve vital business processes all across the enterprise Example of such business processes are presented below
![Page 5: 1 Lecture 7. E-Business and E-Commerce Lecturer: Prof. Anatoly Sachenko Informatics in Logistics Management.](https://reader030.fdocuments.net/reader030/viewer/2022032704/56649d6b5503460f94a49e7f/html5/thumbnails/5.jpg)

Cross-Functional Enterprise Applications (continued)
Figure on next slide is an excellent illustration of the concept of enterprise application architecture
It illustrates the interrelationships of the major cross-functional enterprise applications that many companies have or are installing today
This architecture spotlights the roles that e-business systems play in supporting the customers
Focused on accomplishing fundamental business processes in concert with the company’s customer, supplier, partner, & employee stakeholders

Cross-Functional Enterprise Applications (continued)
Enterprise resource planning (ERP) concentrates on the efficiency of a firm’s internal production.. Distribution. And financial processes.
Customer relationship management (CRM) focuses on acquiring and retaining profitable customers via marketing. Sales. And service processes.
Partner relationship (PRM) aims at acquiring and retaining partners who can enhance the selling and distribution of a firm’s products and services.
Supply chain management (SCM) focuses on developing the most efficient and effective sourcing and procurement processes with suppliers for the products and services needed by a business.
Knowledge management (KM) applications focus on providing a firm’s employees with tools that support group collaboration and decision support.

Enterprise Application Integration
How does a business interconnect some of the cross functional enterprise systems?
Enterprise application integration (EAI) software is being used by many companies to connect their major e-business applications (next slide).
EAI software enables users to model the business processes involved in the interactions that should occur between business applications
EAI also provides middleware thatPerforms data conversion & coordinationProvides application communication & messaging services
Provides access to the application interfaces

Introduction to e-Commerce
Few concepts have revolutionized business more profoundly than e-commerce
E-commerce is the online process of developing, marketing, selling, delivering, servicing, and paying for products & services transacted on internetworked, global marketplaces of customers, with the support of a worldwide network of business partners
![Page 20: 1 Lecture 7. E-Business and E-Commerce Lecturer: Prof. Anatoly Sachenko Informatics in Logistics Management.](https://reader030.fdocuments.net/reader030/viewer/2022032704/56649d6b5503460f94a49e7f/html5/thumbnails/20.jpg)

Introduction to e-Commerce (continued)
E-commerce systems rely on the resources of the Internet, intranets, extranets, and other computer networks. Electronic commerce can include:Interactive marketing, ordering, payment, and
customer support processes at e-commerce sites on the World Wide Web
Extranet access of inventory databases by customers and suppliers
Intranet access of customer relationship management systems by sales and customer service reps
Customer collaboration in product development via Internet newsgroups and e-mail exchanges
![Page 21: 1 Lecture 7. E-Business and E-Commerce Lecturer: Prof. Anatoly Sachenko Informatics in Logistics Management.](https://reader030.fdocuments.net/reader030/viewer/2022032704/56649d6b5503460f94a49e7f/html5/thumbnails/21.jpg)
21
The Scope of e-Commerce
Companies involved in e-commerce as either buyers or sellers rely on Internet-based technologies and e-commerce applications and services to accomplish marketing, discovery, transaction processing, and product and customer service processes.
Three Basic Categories Business-to-Consumer (B2C) Business-to-Business (B2B) Consumer-to-Consumer (C2C)
![Page 22: 1 Lecture 7. E-Business and E-Commerce Lecturer: Prof. Anatoly Sachenko Informatics in Logistics Management.](https://reader030.fdocuments.net/reader030/viewer/2022032704/56649d6b5503460f94a49e7f/html5/thumbnails/22.jpg)
22
The Scope of e-Commerce(continued)
Business-to-Consumer (B2C) – in this form of e- commerce, businesses must develop attractive electronic marketplaces to entice and sell products and services to customers. Companies may offer e-commerce websites that provide virtual
storefronts and multimedia catalogues. Interactive order processing Secure electronic payment systems Online customer support
![Page 23: 1 Lecture 7. E-Business and E-Commerce Lecturer: Prof. Anatoly Sachenko Informatics in Logistics Management.](https://reader030.fdocuments.net/reader030/viewer/2022032704/56649d6b5503460f94a49e7f/html5/thumbnails/23.jpg)
23
The Scope of e-Commerce(continued)
Business-to-Business (B2B) – this category of electronic commerce involves both electronic business marketplaces and direct market links between businesses. Companies may offer:
Secure Internet or extranet e-commerce websites for their business customers/suppliers.
Electronic data interchange (EDI) via the Internet or extranets for computer-to-computer exchange of e-commerce documents with their larger business customers and suppliers.
B2B e-commerce portals that provide auction and exchange markets for businesses.
![Page 24: 1 Lecture 7. E-Business and E-Commerce Lecturer: Prof. Anatoly Sachenko Informatics in Logistics Management.](https://reader030.fdocuments.net/reader030/viewer/2022032704/56649d6b5503460f94a49e7f/html5/thumbnails/24.jpg)
24
The Scope of e-Commerce(continued)
Consumer-to-Consumer (C2C) e-Commerce – successes of online auctions like e-Bay, allow consumers (and businesses) to buy and sell with each other in an auction process at an auction website. Online consumer or business auctions are an
important e-commerce alternative for B2C or B2B e-commerce.
Electronic personal advertising of products or services to buy or sell by consumers at electronic newspaper sites, consumer e-commerce portals, or personal websites is an important form of C2C e-commerce.

systems
![Page 37: 1 Lecture 7. E-Business and E-Commerce Lecturer: Prof. Anatoly Sachenko Informatics in Logistics Management.](https://reader030.fdocuments.net/reader030/viewer/2022032704/56649d6b5503460f94a49e7f/html5/thumbnails/37.jpg)
37
Electronic Payment Processes - Secure Electronic Payments
Secure electronic payments – when you make an online purchase on the Internet, your credit card info is vulnerable to interception by network sniffers SW that easily recognizes credit card number
formats Several basic security measures are being used to
solve this security problem. They include: Encrypt data passing between customer and
merchant Encrypt the data passing between the customer
and the company authorizing the credit card transaction
Take sensitive information offline (cont-d)
![Page 38: 1 Lecture 7. E-Business and E-Commerce Lecturer: Prof. Anatoly Sachenko Informatics in Logistics Management.](https://reader030.fdocuments.net/reader030/viewer/2022032704/56649d6b5503460f94a49e7f/html5/thumbnails/38.jpg)
38
Electronic Payment Processes - Secure Electronic Payments (cont-d)
Secure Socket Layer (SSL) – automatically encrypts data passing between your web browser and a merchant’s server.
Digital Wallet – you add security software add-on modules to your web browser. This enables your browser to encrypt your credit card data in such a way that only the bank that authorizes credit card transactions for the merchant can see it.
Secure Electronic Transaction standard (SET) – software encrypts a digital envelope of digital certificates specifying the payment details for each transaction. SET is expected to become the dominant standard for secure electronic payments on the Internet.
