While the word "integrity" connotes "wholeness", it's important to understand what it means specifically in the case of relational database design. Failure to ensure data integrity can result in the database returning incorrect results, or in data becoming unretrievable. This is true of all relational databases, not just MySQL. Fortunately, the principles of data integrity are not difficult to understand.
