Use Case

Background Introduction
Second hand textbook has potential market in every university. Although there are many big C2C online selling companies out there, like eBay, some students still prefer to buy locally, which saves the delivery expense and is easier to make a payment.

Description
A local bookstore can deploy a used book sell online website, which utilizes information communication technology and has the convenience provided by local trading. Buyer can check detail of each book on the website before he/she go to the store, and seller can leave a book in the bookstore with predefined price. Each transaction is through the bookstore. Buyer and seller do not have to make an appointment to meet any more.

Scope
This component is a part of an entire online selling system. It builds the entry and update function for bookstore staff, browsing function for buyer to find a correct book.
Online placing sell, order and updating function from buyer or seller are out of the boundary. Also, there is no search function for browser to search a particular book for sell.

Actors & Goals
Bookstore (Direct Actor): Keeps buyer and seller’s membership. Propagate itself, or generate some profit from transaction.
Buyer (Direct Actor): Easy to find a book and get the up-to-date information. Does transaction with less time constrain.
Seller: Get a platform with intense demand. No time constrain as no appointment.

Use Case
1. A seller hand a textbook to the bookstore located near university, and give a price to the book.
2. Bookstore staff takes picture and makes description of that book, classify it to a course. Then upload this sell onto the website. (MVC and write database)
3. Buyer browses the website, follow the course classification then check all those available books under one course, record a book he/she wants to buy. (MVC with database read)
4. Buyer goes to bookstore, ask for that particular book and pay. (Delete the record in database)
5. Seller is notified to collect money from bookstore.

Extend
 In book’s description, staff uses a multiple choice to mark a book’s current condition. (unbias)
 Bookstore staff can use barcode to identify a particular book.
 Seller can leave and update a description and price directly on the store website.
 Buyer can place an order directly online.

Potential Project Components to Integrate
(This part is not in my individual work, but can be handled by other team member)
 Bookstore can notify seller by email or SMS after book sold.
 A search engine should be built
 A auction function can be used.
 Integrate with library book DB, student account DB and study unit portal (sakai).

Actually the best actor of the bookstore is the library, which keeps a book database, customer (student) database. This also enhances the payment and trust. And the most important thing is that, unlike most second hand bookstores work on large margin or commission fee between buying and selling price, this service can be free to students.

It discusses what we are trying to do in lab in the following chapter. I find it useful when you get confused in doing the lab work.

This chapter covers
■ Mapping requests to Spring controllers
■ Transparently binding form parameters
■ Validating form submissions
■ Adding functionality with interceptors

I think the reasons can be they use different junit.jar files, or my Ant did not configure well. Anyway, the springapp website runs without any problem. I install
Apache Ant version 1.6.5 compiled on July 5 2006

Stop working

http://weg.ee.usyd.edu.au/courses/ebus5003/
This afternoon, I try the course website, but it doesn't work. I can't do the lab without this~~~~!!!!!

Another problem is that I have copied Spring file from lab computer. When I extract it in my desktop at home, it comes out an error. I really need the junit.jar from Spring to continue.

Maybe Saturday is not the right day to work.

Here is a brand new chapter

I install Ubuntu 7.04 on my desktop at home to do this lab. Since I used up all the quota in accessing internet, I downloaded all the software in lab and planned to install them into my Ubuntu just like what we usually do in MS Windows that straight forward. But I am wrong.

Many software in Ubuntu is self-managed by the system. It can automatically download online and install it on a click. But if you'd got a pack on hand to install, it seems not that straight forward.
First, in Ubuntu, you can't use RPM pack used normally in Fedora or some other popular Linux systems. In installation, you just uncompress the pack you downloaded online, and put it somewhere in the system. The hard thing is to specify the environment value. Here is what I added to
~/.bashrc

export JAVA_HOME=/usr/lib/j2sdk1.5-sun
export CLASSPATH=/usr/lib/j2sdk1.5-sun/lib
export PATH=$PATH:/usr/lib/j2sdk1.5-sun/bin
export CATALINA_HOME=/opt/tomcat

There are some reminders when using the lab computer

bash
source /eelabs/ebus5003/profile

In my account, I always have to type these in my terminal to start and work. No idea!!!!

fs listquota
check your disk space

proxy:
http://www.eelab.usyd.edu.au/proxy.pac
In Firefox


build.properties and build.xml should be under the same folder




In step10, make sure to specify where you want to put the log file. In my case, it is like this:

log4j.appender.logfile.File=/opt/tomcat/logs/springapp.log

If you make it wrong, you can't find the file, and nothing indicates it was going wrong!!!!!!!!


Until now, luckily, part1 is finished. I encounter Linux, Ant and Spring. I believe they are good tools once you can set them up.

Turban, E., Leidner, D.,McLean, E., Wetherbe, J., 2006, Information Technology for Management, Transforming Organisations in the Digital Economy, 5th Edition, John Wiley and Sons, New York

LEB 312 - Week 1

• What is the nature and purpose of strategic transformation?

• Using an example:
• Explain the Impact of transformation change on a business’ architecture and infrastructure

• Give other examples of ‘transforming’ industries.


“Fit for purpose”
As technology is continuously improving and customer desires for more, company is involved into a non-stop innovation process, so that to sustain the market share, make profit in the long run.

Game Industry
Online game is the trend of game industry. Customer’s favour is playing with real people instead of machine now. Many popular games are redesigned into online version.
Web server is employed into the game industry as a component. Online payment, security, and online marketing are highly focused by game producer. Staff with special skill in network game design is needed. Latest console is designed to support wireless high speed connection.

Online Education
Network access is available at home. Students want to save time in commuting, and start to study in their free time. So we can see the possible and necessary of online education.
School starts to provide digital material. An enrolment system should be built up, which hardware, software, network & communication devices, information management personnel and database. IT staff is required. Tutor is trained to master basic computer skill, for communication and produce the learning material.


This course focuses much on change in a business environment, especially in network economy. And see how a company reacts to this change. Doing transformation to maintain competitive, getting more profit eventually. The whole structure builds up on EDCF.
