Traditional databases store deterministic data in which there is no room for uncertainty. Uncertain or probabilistic data cannot be represented or stored in these databases. On the other hand, many modern applications require the need to capture and store data with uncertainty. In response to recent demand for the ability to manage and store this type of data, researchers have started exploring techniques to handle probabilistic data in relational databases. Research in this area has focused on aspects of probabilistic data management including: coming up with ways to represent and model uncertain data, querying uncertain data, handling aggregation functions in databases with probabilistic data, and indexing and storage techniques for probabilistic data.
