Integrity Constraint is a very important criterion for keeping data in a consistent manner, almost all previous XML dependencies are introduced to improve the schema and normalization, with a small effort toward improving data instance. This paper summarizes the most important XML integrity constraint notations and data cleaning approaches. In addition, to highlight the shortcoming of these constraints and proved it is limitation for increasing data quality. Finally, introduce the next generation of conditional integrity constraints, which will be held mainly for data cleaning issues.
