  1. e-Commerce Software

  2. e-Commerce Architecture -- multi-tier software architectures • 3-tier architecture: • tier 1: webserver • tier 2: middleware • tier 3: database server • 2-tier architecture: • tier 1: webserver + middleware (servlets) • tier 2: database server • 1-tier architecture: • all rolled into one.

  3. e-Commerce Software Engineering: Presentation vs. Programming • The Presentation vs. Programming problem: • Consider this scenario: • Webpage Designer creates webpage in fancy tool. • Designer hands it over to Programmer. • Programmer inserts CGI (servlet) URLs. • Programmer write CGI code to produce some part of the page. • Designer re-designs the page. • Programmer must re-code URLs, and perhaps CGI. • Programmer and Designer drive each other crazy. • The real problem: how much of page should be program-generated vs. hand-designed?

  4. e-Commerce Software Engineering: two approaches • Program-generated approach: • Advantages: • Flexible up-to-date content, based on database. • Programming is independent. • Easy to maintain consistency with other CGI programs. • High functionality. • Disadvantages: • Difficult to change page appearance (must re-compile). • Difficult to write page appearance code, e.g., out.println ("<table> <tr> <td> <b> blah blah </b> ..."); • Presentation approach: just the reverse.

  5. e-Commerce Software Engineering: one approach • One approach to software engineering: • Designer creates template HTML, specifying which parts can be changed by Designer, independent of programming. • Designer and Programmer agree on program-generated part of page. • Programmer and Designer list events on "submit" and agree on desired program-generated output. • Programmer and Designer get out of each other's hair. • Programmer creates event chart. • Programmer programs, Designer designs. • Programmer and Designer test results, and argue.

  6. e-Commerce Software Engineering: some tips • Create a URL naming convention. • Create an event-naming convention. • Agree on template design to be used across all (or most) pages.

  7. What is e-commerce Software? • Front-end • For Visitors and Customers • Web-based by definition • Backend • For enterprise business managers • Merchandisers, Account Mangers, Customer Support, etc. • Middleware • To interface with existing systems • Customer, Inventory, Credit, Payment and Order Processing systems

  8. e-Commerce Front-end • Web Application Server • Functionality • Personalization and Profiling • Complex, Dynamic Content Presentation • Process Support • Shopping Process • Buying Process

  9. e-Commerce Backend • Content Management • Merchandizing • Catalog management • Price and on-line collateral management • Process Support • Customer Support • Anomaly management • Payment or Order processing hiccups

  10. e-Commerce Middleware • Payment Processing • Customer specific credit, purchase orders, etc. • Electronic payment including EDI and credit cards • Order Processing • Interface to proprietary, custom enterprise systems • e-enabled systems of large warehouses • e-Services that provide Order Distribution • Inventory Management • Soft and hard reserve functionality • Direct access to specific inventory

  11. The critical success factors • Backend System Management Functionality • Support for workflow and process management • Appropriate use of technology for process support • Access control in content management • Business rules in anomaly management • On-line collateral Management • Images, Audio, or Video; for virtual examination • Structured; for comparison shopping

  12. What’s missing? • Community • Polls, Message Boards, Chats, etc. • Services • Fee email, Consumer news and information, etc. • Marketing Campaign Management • Referrals, Affiliates, Banner ads, Emails, etc. • Hot features of the day • ‘Amazon innovations’ • Mobile commerce • Shopping robots

  13. What about services? • Shopping Portals • Process Re-engineering • e-Services • Branding • On-line collateral development and management • Search engine placement optimization • Efficiency improvements in web delivery

  14. Core Solution Requirements • Database • Oracle • Microsoft SQL Server • Application Servers • With integrated or separate web server • General purposes AppServers • BEA’s WebLogic, IBM’s WebSphere, Microsoft’s ASP • Specific AppServers • BroadVision, ART Technology Group, Oracle

  15. Important Technologies • Everything from the two 400 lbs gorillas • Oracle • Microsoft • DHTML • Microsoft won the browser wars in e-business • XML • Microsoft’s and IBM’s support for SOAP is promising • webMethods is proving the value in inter-application communications • Java • Server side – J2EE, JavaBeans, JSP
