Databases that include these records have often some errors which cause the matching problem in duplicate records becomes a complex problem. These errors are: typing errors, incomplete information such as abbreviations, ignoring of standard formats or a combination of the above factors. In this book, databases are used in which typing errors are more than other errors.
