Answer :
When validating data entered into a date field like "01/04/2023," two common validation checks that could be used are:
1. **Format Check:** This validation ensures that the date is entered in the correct format. For the example given, "01/04/2023," the format should be in the form of "dd/mm/yyyy." In this case, the day (dd) should be between 01 and 31, the month (mm) should be between 01 and 12, and the year (yyyy) should be a valid year. This check helps ensure consistency and accuracy in the date entered.
2. **Range Check:** This validation checks if the entered date falls within an acceptable range. For instance, the date "01/04/2023" should not be in the future (after the current date) if that is a restriction. It could also verify that the date is within a specific range required for the system or application. This check helps prevent illogical or erroneous dates from being entered.
By employing these two validation checks, data integrity and accuracy within the date field can be maintained effectively.
