Official Objectives Knowing e-business systems architectures, at the various levels Understanding the design flow Being able to make qualitative and quantitative evaluations Developing a common ground: For computer science-oriented students : developing a framework of the various technologies For management-oriented students : being able to communicate and understand computerpeople 08/10/09 ebwa-intro 8

Note E-business in the widest sense Economical (and material) transactions, mediated through web applications Not only Electronic Commerce Also includes Intranet applications 08/10/09 ebwa-intro 9

Real objectives Destroy some myths about e-business Frighten system administrators (and their bosses) Inflate budgets Handling the unforeseeable...in other words preventing disasters 08/10/09 ebwa-intro 10

Some e-business myths The important is being on-line, the rest will follow Just a home P.C. is enough to create a web site In a couple of days I ll implement it I tested it: it works I finished it: I go gome Everybody uses Windows HTML is a standard language 08/10/09 ebwa-intro 11

The real word is different... The users Functionality Flexibility Portability Reliability Security Integrity Costs Maintenance Development times Interactions with existing systems Interactions with the physical world Maintenance Performance Scalability 08/10/09 ebwa-intro 12

How to survive? Plan Anticipate all aspects List you priorities Analyze all alternatives Estimate development costs Ensure the necessary resources Prevent Identify failure causes and prepare solutions Measure workload and avoid saturation Be involved in political decisions 08/10/09 ebwa-intro 13

How to survive? Aim at the highest-quality, or better: In reliability In designing the User Interface In the website response time In graphics and textual parts In integrating logistic services In integrating payment services In customer care 08/10/09 ebwa-intro 14

Conceptual flow Service objectives Design elements Functional specifications Quantitative parameters Software requirements Hardware requirements Network requirements 08/10/09 ebwa-intro 15

Prerequisites Notions of Internetworking (TCP/IP, http, DNS) Basic notions of HTML (formatting, anchors, forms) and Internet navigation Basic notions on data bases (relational model, SQL) 08/10/09 ebwa-intro 16

Topics of the course (I) From the www to e-business: historical evolution of Internet applications analysis of the types of web transactions analysis of the related architectures supporting them web, application, database, network & routing, proxies, load balancing, (thin) clients bottom-up process in which we learn about the different components of the architecture and their main characteristics 08/10/09 ebwa-intro 17

Topics of the course (II) In-depth technical topics: The foundations: XHMTL and HTTP Basic technologies and languages for designing static websites Application servers: Internal architectures for supporting dynamic web sites. From simple scripting languages (PHP, ASP, JSP), to application servers (Tomcat, component frameworks), to Enterprise Application servers Thick clients: XML, DOM, CSS, JS, Ajax New paradigms for highly interactive applications 08/10/09 ebwa-intro 18

Topics of the course (III) Designing the web experience Usability General definitions, design criteria, evaluatin methodologies for easy-to-use web applications Information Architecture Design of the conceptual and navigation structure of a website Accessibility Technical solutions for allowing access to web sites to users with a variety of browsing systems and devices, including impaired users 08/10/09 ebwa-intro 19

Topics of the course (IV) Looking to the future Service Oriented Architectures How to build e-business applications integrating services from different providers The Semantic Web Allowing machines to understand and reason about the contents provided by web systems The Web 2.0 Integrated and highly interactive applications based on syndication, linking, tagging, social contributions,... (e.g., blogs, folksonomies,...) 08/10/09 ebwa-intro 20

Practical exercises Designing simple web pages Designing functional and navigation structures of existing or hypothetical websites Sizing and scaling numerical exercises Hands-on experience with real web applications (CMS, ERP, CRM) 08/10/09 ebwa-intro 21
