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\.
