Uncertain Databases is a database system that extends the traditional relational model by incorporating mechanisms to represent and manage data uncertainty, where the presence, values, or relationships of data entries are not precisely known but are instead described through probabilistic, possibilistic, or other formal uncertainty frameworks.
