Some Basic Course Info UG Record Description
History of Internet and electronic commerce on the web; case studies of success and failure; cryptographic techniques for privacy, security, and authentication; digital money; transaction processing; wired and wireless access technologies; Java; streaming multimedia; XML; Bluetooth. Defining, protecting, growing, and raising capital for an e-business.
Counts as: CS or CpE elective (or tech elective) For the SEAS Engin. Business minor
4
What This Means…. CS453 is taught by CS staff for computing students Addresses business and commerce issues
But not a business course Some “business-light”, gain ability to work with those
in that world Addresses technologies needed to make e-commerce
happen Mostly broad coverage, illustrative technologies Not a deep focus on many areas
Not a course in DBMS, web services, web design, security
Technologies that support business needs and issues E.g. session management, secure transactions
Goal: to see how it all fits together
5
Business Issues Focus on Internet commerce
more narrow than e-business Topics and issues
What does the Internet offer a business? Business models, strategies, goals
Successes and failures Issues facing new companies, startups What business needs drive technical
solutions? Legal and ethical issues: IP, patents,
privacy, etc. Sources:
Readings, articles, etc. (Maybe speakers)
6
Technical Topics Some history and fundamentals about the Internet and
the Web Presentation topics (HTML, CSS, Javascript) Web interactions (CGI, PHP, etc.) Web servers: some basic Apache (maybe) XML, Web services (maybe) Javascript libraries Cryptography; Security; Reliability Payment systems; Shopping carts; Order Management
XML and Web Services; Cryptography; Security; Payment Systems; etc.

Course Philosophy Maybe you’re near the end of your studies here This course has an applied, real-world focus in a
rapidly-changing area. Therefore:
Focus on real-world issues and technologies Give you choices to let you be more
motivated Treat you like mature and independent
students/professionals Student input and participation in the day-to-
day course Allow and motivate you to be more self-
directed learners Have fun
8
Applying the Course Philosophy (1) Learning as exploration
As opposed to marching through a set of required topics and skills
Self-motivated learning Focus on important, interesting, authentic,
real-world technologies and problems You’ll get choice and flexibility in
HW focus (e.g. business vs. technology) Tools and techniques you learn
I’ll treat you as independent and mature computing students and professionals (next slide)
9
Applying the Course Philosophy (2) I’ll treat you like independent and mature
computing students and professionals No hand-holding needed You’re able to learn-languages, tools, etc. on
your own from good sources With help from your team (staff and other
students) when needed You can install and administer your own SW
tools and environments E.g. WAMP, etc
You are able to define goals, manage your time, report findings/problems, communicate
10
Applying the Course Philosophy (3) Together let’s address CS453 as a team
Students know things I don’t know—embrace that
Learning together is more fun than working alone
My goal is to turn this into a course good for me and for students
Your help needed (and required)
And let’s not forget we want to: Learn useful things Deal with authentic real-world problems and
technologies Have fun
11
Class Sessions Some lecture
More than there should be Some presentations (maybe not in summer)
Industry, commerce experts E-commerce research:
Auctions, search engines, etc. More discussion than other classes Some active learning activities
Problem discussions, debates Quick research and report at next class Quick team-up/think/opine Quick quiz or survey
12
Class Input: Business How many of you are business minors?
What engin. business courses have you taken?
How many of you have worked in e-business?
13
What Business or E-business Topics should be addressed?
First, from “student business experts” Then, from anyone
14
15
TechnologiesSome are required
(at a basic level):
HTML, CSS JavaScript PHP Some security
technologies SQL and mySQL Client/server
applications Maybe a
framework like symfony
Some are “optional”: Web services .NET, ASP, C# etc. JSEE Flash, multimedia Perl, Python, Ruby More security XML Web 2.0, Ajax Ruby on Rails
16
Class Input1. What else might be on this list that’s not?2. How many know a lot or some about any of
these?3. What do you want to learn?

OK, maybe not the things in red And can we really do justice to things in that last
sentence? Comments?

Virtual Labs Virtual labs offer anywhere/anytime instruction
and practice with our technical topics We are eager for you to derive a substantial
benefit from all this invested effort Labs are highly recommended but not required
Except that they are a great resource for your E-Portfolio

Homeworks: 60% of grade Some flexibility in later homeworks Some assignments can be in groups of two or
three (may require extra things) Topics and weights (provisional)
1. Case study of an e-commerce enterprise: 10%2. JavaScript programming: 10%3. PHP, Forms, Encryption: 10%4. Choice of larger technical problem/project:
20%5. Choice of technical problem or e-commerce
problem: 10% Some comments on HW4 and HW5 in next
slides…
23
HW4: larger technical project In the past… Themes:
a fully functioning e-store a fully functional web-based e-service a fully functional m-commerce system
Develop applications for medicine, education, gaming, social networking, government (e-voting), convenience, something experimental or revolutionary
Use toolsets appropriate to the project Possibly partner with a professor’s research,
etc.
24
HW5: examples from the past a super-in-depth e-commerce case study a high-quality, realistic, achievable business
plan for a legitimate e-commerce venture high-quality presentation or tutorial on an
sophisticated technical topic something we decide to add to this list as we
go along Variations / projects are possible
Propose something to me if you wish!
[Not this term!] mock trial for patent infringement

Curving: Curves may beapplied to exam scores etc.
28
Honor System All homeworks and exams will contain explicit
language regarding what is or what is not permissible
I will assume that everyone abides by the tenets of the honor system
In all your work, cite all your sources (whether in code or prose)
29
Textbooks and References
30
Names It is my personal goal to learn everyone’s
name You need to help by identifying yourself to
me until I can reliably call you by name Name badges
Don’t be surprised if we use these for a few weeks
At least initially, please identify yourself by name when asking/answering questions so everyone can learn all our names
31
Questions?
32
Activity Two debates:
1. Is Google Evil?2. Should Yahoo release personal info to the
Chinese government? Do you know about these issues?
Eight groups of 5 or so. Half on Google, half on Yahoo
Report a conclusion for your group with reasons Minority opinions allowed afterwards
Go!
(Notes from discussion) Google: many services (mail, blogs, search,
docs, code, phones/android, netbooks Google analytics
Companies and governments
