Data validation and verification techniques
Validation check is when data is input to a computer, the computer must check if the data is sensible, for example date of birth not in the future. Different validation checks can be used on different fields depending on the type of data being entered. We can use the presence check to make sure that the data is present and not missed out, we can also check if the data is within the range, for example exam percentage should be between 0% and 100%, a month should be between 1 and 12. Moreover type check can be used to make sure that the data is off the correct type, an example is Letters should not be allowed in numeric field. There is also length check if the data is too short or long and this can be used in phone numbers or Visa numbers. Finally format check to make sure that data is off correct format.
Now speaking about verification it checks whether the data entered is sensible but that does not mean that the data is correct for example entering the date 30/10/1928 instead of 30/10/1982 will not be an error as it is a valid date. So to check that the data is correct we can use proof reading; after the data has been entered a person compares the original data with the data in the computer, this way is quick and simple but doesn’t catch every mistake. Another method is Double-entry where data will be entered twice (preferably by two different people). Then the computer compares the two sets of data to see if they match, if not then a person will correct the mistake but this method takes more time and effort but it catches almost every mistake. A common example is when you set a new password you need to tye it twice to make sure it’s typed correctly.

Answer / thinktest
Verification:
Definition: It is a static testing that mean testing a product without executing it (through Walk through, Inspection and Review etc). It helps in finding out the defects with the location of defect. It is a process oriented.
Key Objective: Are we building the product right?
Evaluation Item: Plan, Requirement, Design, Code, Test Cases etc)
Activity: Review, Instection, Walkthrough
Validation:
Definition: It is a dynamic testing that mean testing a product by executing it (through Integration testing, System Testing etc). It helps in finding out the defect only and not its location. It is a product oriented.
Key Objective: Are we building the right product?
Evaluation Item: Actual Product, Software
Activity: Testing

Answer / swapnil gour
This model executes in 2 phases i.e. 1st the verification starts & then validation takes place.
Since, execution happens in V shape it is known as V model.
•1st all the activity goes in downward flow
• we prepare necessary test documents at every stage
• at certain stage,we come back and make use of document and start testing.

Answer / anjani dubey
Verification is the process of doing reviews and
walkthroughs and conducting interviews.
This is doing before coding phase.
Validation is the process of doing actual testing in the
source code.
This is always starting after coding in SDLC.
