Data or Input validation in MDriven ensures that data entered by users is correct, consistent, and conforms to the business rules of the application before being processed or persisted in the database.

Data validation is important in for the reasons:

Data Integrity
Enforcing business rules
Data Security

Common Types of Data Validation used by MDriven:

Required Fields: self.FirstName->IsEmpty implies "FirstName is required" (Field should not be left empty)
Data type validation: this can be by ensuring the correct data type in selected for the model attribute (String, Date, Datetime, decimal, Float,Blob e.t.c).
Range validation (self.DayOfBirth > 0) and (self.DayOfBirth < 32). The system only expects values between 0 - 31 excluding 0 and 32.
Format validation such regular expressions for emails self.EmailAddress.regExpMatch('^[a-zA-Z0-9+_.-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,3}$').
Conditional validations.
