Handling uncertainty and incompleteness of knowledge becomes a challenging task in information systems. Rough-set theory enhances databases by allowing it for the management of uncertainty. Roughsets, due to its versatality can be integrated into an underlying database model like relational or object oriented which can also be used in the design and querying of databases. The researchers extended relational databases to introduce rough relational databases. Rough Relational DataBases (RRDB) are those databases that can have multi-valued attributes.
