SeeSys System Background

• ATT Bell Labortories
• Large Scale Software Applications/Projects
• Really Implements Treemaps

3
Introduction

• A way to visualize a large scale software
  application and its sub-parts for statistical
  research
• WOW BACK UP!!!!

4
Favorite Sentence

• This technique can display the relative sizes of
  the location of new functionality, and the
  location of error-prone code with many bug fixes.

5
Demonstration

• An Example
• Makes No Sense yet

6
Bottom Line

• Large Software Projects
• Many Sub Parts/Systems
• Many Files
• Many Programmers
• Why? Analysis

7
Metrics for Measurement

• Errors in code
• System Evolution
• Recurrence of Errors

8
An Example

• Assume
• We Create

• New Release
• A Database
• - Contains certain Metrics

9
What we want to know?

• Largest? Activity?
• Structure? allocation
• Errors? location
• Where we focus effort?
• Growth Rate?

10
USER INTERACTION?

• Mouse

11
Legacies of the Project

• Color
• Spatial Utilization
• Zoom in and Zoom out capabilities

12
Resources

• References mostly stuff about graphs and
  visualization
• Lots of IEEE Articles

13
Critiques - Strengths

• Addresses the heart of the issue
• Doesnt try to conquer too much
• Makes Project Management very easy
• Dont need to know much about a project

14
Critiques - Weaknesses

• Speaks about only one system
• No under the hood details
• Questions about the implementation
