2. Types of Data Validation
As per the statistics, most of the organizations not using data validation experience data entry error
rate of 2% to 8%. Maximum invalid data situations are caused by users entering incorrect data in the
online web forms and user interactivity screens.
Data validation is the process of checking database to ensure that the information gathered from
different data sources is clean, accurate and in a standard format. Data validation can be simple or
complex, depending upon the way it is performed. For example, validating email address, or phone
numbers is easy. On the other hand, checking different data fields for consistency and accuracy in a
master database will be complex.
In a nutshell, data needs to be validated at the same stage/level where it’s most likely to be
erroneous. Following is the description of different types of data validation techniques:
Form Level Validation: It ensures that all the fields marked as mandatory
in the web form are filled correctly before the user clicks the submit button on
the page
Field Level Validation: It makes certain that users enter correct value
across a specific data field. For example, “Name” field can’t have a numeric
value, and “email” field should contain a value having “.” and “@”
Data Saving Validation: Data saving validation is used for multiple data
entry forms and option screens. User is allowed to save data on any or all
tabs/pages before leaving the page
Search Criteria Validation: This type of validation is used when there are
multiple search criteria in a form, and user wants to save the search results
before navigating to a different page
Range Validation: This validation type is used to make sure that the
numeric value, characters or date entered is within the specific range
Data validation authenticates the data for duplicate information, incorrect formats, typos,
grammatical and punctuation errors. It is an effective technique to keep the data up-to-date and
accurate.
