Techopedia explains Data Validation
Data validation primarily helps in ensuring that the data sent to connected applications is complete, accurate, secure and consistent. This is achieved through data validation's checks and rules that routinely check for the validity of data. These rules are generally defined in a data dictionary or are implemented through data validation software.
Some of the types of data validation include:
- Code validation
- Data type validation
- Data range validation
- Constraint validation
- Structured validation
