Glossary	Definition
Duplication rate	Formula: Duplication rate = Number of duplicate lines of code/Number of lines of code ×100% Duplicate lines of code: identical code in multiple locations within a program. Duplicate blocks: Java: 10 consecutive lines; others: 100 consecutive characters in 10 lines.
Rule	Rules are used to check code, including code issue impact and fix suggestions.
Rule set	A set of check rules defined for specific languages to improve code quality.
Cyclomatic complexity	Formula: Average cyclomatic complexity = Loop complexity/Number of functions A metric used to indicate the code complexity. It has an impact on the code maintainability and testability. A high cyclomatic complexity indicates a high possibility of code errors. Categorization of cyclomatic complexity: 1–5: little risk 6–10: moderate risk 11–20: medium risk 21–50: high risk 51+: extremely high risk NA: not supported language
SDLC	Software development life cycle.
Issue display	A function showing the lines of code where issues are found. Users can view and fix code issues online.
Deferral period	The upgraded check engines may detect new issues. These new issues will be counted if not fixed or masked during a 60-day buffer period.
Execution plan	An automatic triggering mode of check tasks for more flexible, easy to use, and automated check.
