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

20

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

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)

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

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.

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.

Electronic Commerce Technologies - next slide illustrates an e-commerce architecture developed by Sun Microsystems

Scope of e-Commerce (continued)

Electronic commerce technologies (continued) Trading and business partners rely on the Internet

and extranets to exchange information and accomplish secure transactions

Company employees depend on a variety of Internet and intranet resources to communicate and collaborate

IS professionals and end users can use a variety of software tools to develop and manage the content and operations of the websites and other e-commerce resources

27

Essential e-Commerce Processes

Nine key components of an e-commerce process architecture (see next slide) Access control and security Profiling and personalizing Search management Content management Catalog management Payment Workflow management Event notification Collaboration and training

28

Essential e-Commerce Processes(continued)

29

Essential e-Commerce Processes (continued)

Access control and security Processes MUST establish mutual trust and secure

access Authenticating users Authorizing access Enforcing security features

Must protect the resources of e-commerce sites from threats Hackers Theft of passwords or credit card numbers System failures

30

Essential e-Commerce Processes (continued)

Profiling and personalizing One-to-one marketing strategy

Personalized view of the website Based on Personal data, and website behavior

and choices Used to help authenticate your identity for account

management and payment purposesSearch management

Helps customers find the specific product or service they want

SW may include a search engine component or a company may acquire a customized e-commerce search engine

31

Essential e-Commerce Processes (continued)

Content and catalog management Content management software helps

companies develop, generate, deliver, update, and archive text data and multimedia information

Frequently takes the form of multimedia catalogs of product information

Works with profiling tools to personalize the content of the website

May be expanded to include product configuration processes that support mass customization of a company’s products

32

Essential e-Commerce Processes (continued)

Workflow management Workflow software engine

Predefined sets of business rules Roles of stakeholders Authorization requirements and routing alternatives Databases used Sequence of tasks

Workflow systems ensure that..Proper transactions, decisions, & work activities are

performedCorrect data and documents are routed to the right

employees, customers, suppliers, and other business stakeholders

33

Essential e-Commerce Processes (continued)

Event notification Most applications are event driven

New customer’s first visit Payment and delivery processes Customer relationship & supply chain

management activities Notifies those concerned when an event occurs that

might affect their status in a transactionCollaboration and training

Supports the collaboration arrangements & trading services needed by customers, suppliers, & other stakeholders

May be provided by Internet-based trading services

34

Electronic Payment Processes

Processes are complex Near anonymous nature of transactions Security issues Wide variety of debit and credit alternatives Wide variety of financial institutions and

intermediariesWeb payment processes

Credit cards Purchase orders Electronic shopping cart

An example of a secure electronic payment system with many payment alternatives is illustrated on next slide

35

Web Payment Processes

36

Electronic Payment Processes (continued)

Electronic funds transfer (EFT) Uses a variety of IT to capture and process

money and credit transfers between banks and businesses and their customers ATMs and Pay-by-phone Web-based

PayPal & Bill Point (cash transfers) CheckFree and PayTrust (automatic bill

paying services) Electronic bill payment Point-of-sale terminals linked to bank EFT

systems

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)

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.
