Tools and Approach
• Zaurak Oracle8i used to hold database
• Java, JDK1.3, Win-XP/win-NT used for development
• JBuilder used as tool GUI, etc development
Overview
Why Java Bean?
-100% pure java programs.
-simple to develop and easy to use.
-enable well-formed objects to be
manipulated in a builder tool during the
design time
Overview
Why Jbuilder?
- “best of breed” in the rapid application
development tool market.
- fully support for building reusable
components
- visually design GUIs and rapidly build
application.

Contribution
• The implementation of this project will
have positive impacts on CIS 501 and
CIS560 teachings and will help students to
easily implement database java bean
without having further knowledge of using
advanced swing complements and latest
JDBC technology.

Cost Estimates
- Adjusted function points (cont’)
• Adjusted FP = FPunadjusted * (0.65 + 0.01
* (sum of ratings))
= 120 * (0.65+0.01*41)
= 127.2
Cost Estimate
- COCOMO
• KDSI = 2.8 KLOC
PM = 2.4 * (KDSI) ^ 1.05
= 2.4 * 2.8^1.05
= 7.1 (person-month)
TDEV = 2.5 * (PM) ^ 0.38
= 2.5 * 7.1 ^ 0.38
= 5.2 (month)
