Validation checks with Nanoflows
If validation check is done with a Nanoflow, does a validation check become unnecessary with the Microflow? (If it is maliciously tampered with, is it covered by Mendix Security?)
completely depending on goals and implementation.
If you want database level validations, then Either the validation rules at entity level or a microflow as before commit event will do the trick.
Nanoflows is client side logic, and thus client side validations.
