Cyclomatic Complexity

Do not write functions that have high cyclomatic complexity. This makes the code hard to maintain.

Bad code

Any procedure / trigger that has a cyclomatic complexity > 25, using the CC3 version mentioned in [this article][anchor0].  

Good code

Any procedure / trigger that has a cyclomatic complexity <= 25, using the CC3 version.
The CC3 version is computed by summing the following in a code block:
- each IF statement as 1\.
- each entire CASE as 1\.
