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.

7

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?

Demonstration of Learning

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

25

E-commerce company case study: 10% JavaScript: 10% HW3: 10% HW4 (larger technical project): 20% HW5 (choose e-business or technical): 10%

Subject to minor alterations (say +/- 5%) with advance notice to the class

technologies May have in-class and out-of-class portion

Out-of-class may be coding etc. Dates on syllabus (subject to change)

E.g. 91.50 --> 92 91.499999 --> 91

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
