An Entity of Type: Abstraction100002137, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Most real databases contain data whose correctness is uncertain. In order to work with such data, there is a need to quantify the integrity of the data. This is achieved by using probabilistic databases. A probabilistic database is an uncertain database in which the possible worlds have associated probabilities. Probabilistic database management systems are currently an active area of research. "While there are currently no commercial probabilistic database systems, several research prototypes exist..."

Property Value
dbo:abstract
  • Una base de datos probabilística es una base de datos en la que los campos tienen asociados valores de probabilidad. Los gestores de bases de datos probabilísticas son un área de investigación muy activa en la actualidad. Si bien aun no hay productos comerciales, existen diversos prototipos. En las bases de datos probabilísticas se distingue entre el modelo de datos y su representación física, de un modo similar al de una base de datos relacional. En las probabilísticas esta distinción es crucial porque tienen que representar números muy grandes de posibles valores, a veces exponencial.​​ (es)
  • Most real databases contain data whose correctness is uncertain. In order to work with such data, there is a need to quantify the integrity of the data. This is achieved by using probabilistic databases. A probabilistic database is an uncertain database in which the possible worlds have associated probabilities. Probabilistic database management systems are currently an active area of research. "While there are currently no commercial probabilistic database systems, several research prototypes exist..." Probabilistic databases distinguish between the logical data model and the physical representation of the data much like relational databases do in the ANSI-SPARC Architecture.In probabilistic databases this is even more crucial since such databases have to represent very large numbers of possible worlds, often exponential in the size of one world (a classical database), succinctly.
