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 best refers to?

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.


What is typical data?

data which can be stored easily. - OR - Typical data you enter into a computer system which satisfies the validation and verification rules in place.


What data validation can be used in a database?

A database is only as useful as the data it contains. Validation helps prevent invalid or inconsistent data from getting stored. At the most elementary level, it could be as simple are requiring a given element to only contain numerical data. More complex validation rules might entail a list of valid values, cross-field edits (if field A contains "xyz", then field B cannot contain "abc") and various more complex rules known as constraints (such as foreign key and NOT NULL rules.)


How critical is validation when it comes to program performance?

Validation should always be considered in a software program. The amount of validation depends on what the program is doing, and how it is doing it. If the validation is a small percentage of the overall program then it doesn't matter much how efficient it is in terms of performance. There are good and bad ways (actually inefficient ways) to do validation. If you instrument a program and find that a significant portion of the time is spent in validation you may want to visit the algorithms used in the validation to see if there is a more effective way to do this. In some cases the performance of validation of data is very important; in other cases it is a side-effect.


What is the difference between computer data represented by the state of a computer's electrical switches and the meaningful information that is displayed to the user?

Information requires a mind, data is a series of states in the computer. It's like the difference between hearing and listening, one requires a mind the other doesn't.

Can anyone share a data validation process?

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

Difference between data validation and data verification?

Data validation means to check for correctness, meaningfulness, and security of data that are input to the system. The simplest data validation verifies that the characters provided come from a valid set. For example, telephone numbers should include the digits and possibly the characters +, -, (, and ) (plus, minus, and brackets). A more sophisticated data validation routine would check to see the user had entered a valid country code, i.e., that the number of digits entered matched the convention for the country or area specified. Data validation might also check that all required fields are filled in before an online form was submitted. Data validation should also check that only data of an appropriate length is accepted. Failure to do so can make an application vulnerable to buffer overflow exploits. Validation should also prevent users from entering command strings in place of data. Data verification is a process that helps to determine whether data was accurately translated when data is transported from one source to another, is complete, and supports processes in the new system. During verification, there may be a need for a parallel run of both systems to identify areas of disparity and forestall erroneous data loss.
