What is UCC?
• Counts lines of code in so;ware source files • Key coun?ng capabili?es • Physical/Logical SLOC • Blank Lines, Comments • Compiler Direc?ves, Executable Instruc?ons • Keywords • Cycloma?c Complexity • Differencing • Duplicates • Custom extensions
Opera?onal Concepts
USC DR Students
• 40-‐50 Graduate students • 5-‐10 hours/week • 5 – 8 projects per semester
• Added Func?onality • Addi?onal Metrics • New Language Support • Maintenance • Integra?on • Process Improvement
The Aerospace Corpora@on
• Evaluate code for buffer overflows and vulnerabili?es
• Work closely with client to pass security filters, making required changes
• Independent Verifica?on & Valida?on
UCC Development and Deliverables
Development Phases
• Research and Documenta?on
• Implementa?on and Tes?ng • Extensive Tes?ng and
Documenta?on • Integra?on and System
Tes?ng
Semester Deliverables
• Timesheets (hours) • Project Plan • Weekly Status Reports • Source Code • Test Cases • Test Code • Final Report
