In this survey, we will visit existing projects and proposals for uncertain data, all supporting probabilistic handling of confidence scores.
Several models for uncertain data have been proposed over the years. Initial efforts all focused on relational data  and also currently efforts are being made in the relational setting [10,4,5,7,2]. With relational data models, two methods to associate confidences with data are commonly used.
