ProbDB (Probabilistic Database) is a probabilistic data management system to manage uncertain data on top of relational DBMSs. One of the main features of the prototype is its portability; that means with a minimum effort it can be implemented over any DBMS. In ProbDB, we take advantage of the functionalities provided by almost all DBMSs, particularly the query processing functions. When a probabilistic query is issued, ProbDB divides the query into two parts: probabilistic and deterministic (i.e. non probabilistic) parts. The deterministic part is executed by the underlying DBMS, and the rest of work is done by our probabilistic query processing algorithms which are executed over the data returned by DBMS.
