A validation rule is simply to make sure that the data is entered correctly into the database (go onto bitesize-ICT-validation and verification for more info)
The validation rule is used in completing online shopping as it is a means of verification of identity and confirming legal and authorized transaction.
Yes, but it depends on the validation routines used.
Validation.
No, there is no distinction between Digital Validation Document DV and Folder DV. "Digital Validation Document" is a general term referring to any digital record used for validation, regardless of its format or where it is stored.
types of validations are: required field validation range validation pattern matching validation database specific validation numeric validation
Declarative form validation involves defining validation rules directly within the markup or structure of a form, often using attributes or annotations to specify constraints. This approach allows for automatic handling of validation by the framework or library being used, making it easier to read and maintain. In contrast, programmatic form validation involves writing custom validation logic in the code, allowing for more complex and dynamic validation scenarios tailored to specific requirements. This method offers greater flexibility but can increase complexity in implementation.

Validation should always be considered in a software program. The amount of validation depends on what the program is doing, and how it is doing it. If the validation is a small percentage of the overall program then it doesn't matter much how efficient it is in terms of performance. There are good and bad ways (actually inefficient ways) to do validation. If you instrument a program and find that a significant portion of the time is spent in validation you may want to visit the algorithms used in the validation to see if there is a more effective way to do this. In some cases the performance of validation of data is very important; in other cases it is a side-effect.
