<human>:  With regards to the concept of Data Integrity, how do you define it?
<bot>: Data Integrity is the property that data is not corrupted or tampered with in any way. Data integrity is a very important property for a database, since if data is corrupted or tampered with, it can cause serious problems. For example, if a person adds a new row to a database table, then changes the values of existing rows to something different, the database will no longer be able to properly function.
