What is the purpose of validation in data entry?

The purpose of validation in data entry is primarily to ensure that the data input is reasonable and meets predefined criteria or standards. This process involves checking the accuracy and quality of the data before it is entered into a system, thereby preventing errors and ensuring the integrity of the data.

Validation serves as a critical checkpoint to verify that the data conforms to expected formats, ranges, and conditions. For instance, if a field requires a date, validation helps to ensure that the entry is indeed a valid date and not an incorrect string of characters. This not only enhances the overall reliability of the dataset but also assures that the data collected can be trusted for analysis and decision-making.

While eliminating redundancy, reducing storage requirements, and enhancing processing speed are valuable aspects of data management, they are not the central focus of the validation process in data entry. Validation specifically targets the accuracy and reasonableness of data to prevent erroneous information from entering the data management system.
