2. 1. Agile Software Development
Agile software development is
- Different from
http://en.wikipedia.org/wiki/Agile_software_development
- I mean just “agile”. Quick and Clean development.

3. 2. In early web.
PHP : Personal Home Page Tools (1995)
ASP : Active Server Page (1998)
JSP : Java Server Page (2003)
All just for Expression! Show text & photo.
That doesn’t require professional programming
skill.

In 1998, many company has crushed (I.M.F).
>> Web programmer Bigbang! IT does not require such
big capital.

5. 2. In early web. (cont)
Due to high popularity of Web programmer, the rewards
become lower and lower.
>> Most of programmer stop learning web. (find another
job)

6. 3. After they stop learning…
• High speed internet line spread into home.
• Hardware price came down.
• Software crisis(early software does not support bug-
fix).
• Software engineering(people want to develop software
efficiently).
• Many input-device has developed(Web cam, Screen
reader, Smart phone, Barcode reader, Touch screen,
NFC, RFID).
• Wireless network has developed(Now-2013-LTE
speed : 2MB/s)

7. 3. After they stop learning(cont)
• Innovation!
By (Google Chrome, Apple Iphone), we can make high
tech web software!
• Web 2.0
connect. Web is Web.
Web is not “showcase”, but “Platform”.

8. 4. Web 2.0 (Important)
The WEB.
- Rich Internet application (3D, Sound, Gyro~)

a programming paradigm that represents concepts as
"objects" that have data fields (attributes that
