[Maintainability Index][anchor0]: Do not write functions that have a very low maintainability index. This makes the code hard to maintain.
|
|
|
|
Bad code
|
|
|
|
Any procedure / trigger that has a maintainability index < 20
|
|
|
|
|
|
|
|
Good code
|
|
|
|
Any procedure / trigger that has a maintainability index \>= 20\.
|
|
The Maintainability Index is computed as a function:
|
|
- Lines Of Code (inverse proportional)
|
|
- the Halstead Volume
|
|
- Cyclomatic Complexity (inverse proportional).
