MayBMS: A Database Management System for Uncertain and Probabilistic Data

September 2007 to August 2012
MayBMS logo

Uncertain data arises often in practice. Examples include scientific databases, data integration, sensor data management, as well as scenarios where information is manually entered and is therefore prone to mistakes and incompleteness. MayBMS is a probabilistic database management system. Its main features include (among others) a powerful query language for processing and transforming uncertain data, space-efficient representation and storage, and support for data cleaning.

Efficient query processing techniques for probabilistic databases, which are also integrated in MayBMS, form the subject of a more specific project called SPROUT.
