What is meant by Validity checks?
Validity checks are an essential part of data validation and verification in software applications. They ensure that the entered data or parameters meet the expected requirements and are correct. Validity checks help identify and prevent data errors, inconsistencies, or undesired values.
Typical functions of software in the "validity checks" domain are:
- Data format validation: The software verifies whether the entered data conforms to the expected format, such as date, number, text, or other data types.
- Range validation: The software checks whether the entered data falls within a valid range, such as whether a number is within a defined range of values.
- Plausibility check: The software verifies the plausibility of the entered data by checking logical relationships between different data fields or attributes.
- Duplicate detection: The software detects and prevents the entry of duplicates in a dataset to ensure data consistency.
- Referential integrity check: The software verifies whether reference data or links between different records or tables are consistent.
- Business rule validation: The software checks whether the entered data comply with defined business rules or requirements.
- Custom validations: The software allows for defining and applying custom validity checks or rules specific to the application's requirements.
- Error messaging and feedback: The software displays error messages or warnings to the user when a validity check fails and provides feedback for correcting the data.
