Why to keep data up to date and relevant.

Practical reasons: It's easier to do anything with data that is relevant, as it will all be correct and you'll never have to chase information to see if it's accurate.

Legal reasons: Under the Data Protection Act (1998) it is a legal requirement to keep all data up to date that is relevant, like address, phone number etc.

Usefulness reasons: If it's not up to date then the data won't be useful for anything.


Evaluate the importance of quality of data when developing a database.


Quality of data is important when developing a database because if the data isn't up to date then the functions of the database would be useless.If the quality isn't good, the the results won't be any good, making the whole system redundant. It would also be illegal if the data wasn't up to date under the Data Protection Act (1998), making the whole database illegal and not usable.
