Basically its used normally at point of input. I.e when the user enters data. The field is set to accept a certain type of data for example a date. the format is dd/mm/yyyy (European format). In most systems you can set the date input format automatically however, the validation is the the date in a programmed field can be the format entry and if its different to that shown for instance 12/03/15 the entry is not valid and a warning can be shown. . The validation would also be =>DATE. date being the day of use. Again the validation would fail if I tried to input yesterdays date. Common ones are inputs which cannot be greater than a certain figure, start dates must not be greater than end dates to name just some. inputs masks such as the dat format are also used to great effect for telepone numbers, zip/post codes and of course dates
Data Validation is a process of Cleaning and Validation of the data base. It is performed by checking for inconsistent and misplaced data with the help of electronic and manual checks. A Data Validation Process may include: Removal of invalid information Removal of duplications Identification of missing information Remove typographic, grammatical and punctuation errors
In order to conduct a research data validation is very necessary. Without the authentic data validation research is incomplete and worthless.
batch validation is a programmed validation to achieve valid data. its done after data entry and before data cleaning. batch validation can be over night process or day process.
Data validation.
one is a validation the other is redundancy clue is in the name
data validation is when data is collected and stored for after use.
Data validation makes sure that the data is clean, correct and meaningful, while data verification ensures that all copies of the data are as good as the original.
Data Validation is a process that ensures that data entered into the database form, a web form, or a computer program conforms to the correct data type.

if it is valid or not
Range validation is a type of data validation that checks if a value falls within a specific range or set of values. It ensures that data input is within acceptable boundaries, preventing invalid or out-of-range values from being processed. Range validation helps maintain data integrity and accuracy in systems and applications.
