Effects of Inaccurate Data Inaccurate data will affect the system in many ways. Data Effect Way it can be prevented Spelling mistakes (website).If spelling mistakes are made then wrong information might be given out and also the guests will think this agency is not a professional one.

Not ever-changing the colour of hyperlinksIf hyperlinks do not change colour then the customer will not no which site he has been to so he will go on that website repeatedly.

And there wont be any inaccurate data constitution Validation is to make sure that data which is being entered should be reasonable and allowable meaning that it is something possible but it doesnt have to be correct.There are a few different types of validations to help reduce the number of errors made by a user Type check, range check, picture or format check, check digit, field length checks etc. halt The validation can be used to make sure that when a user types data in the computer and if there are any errors made in the typing then they are reduced. For example if a database was going to be made with mistakes like if a 1993 date of produce was typed and was not true, the computer will not take it as an error if was programmed to le t in anything between 1990 and1994. So the results would be incorrect and full of mistakes.This could also be known as Garbage In, Garbage out (GIGO).
