In the last decades, the amount of collected data in information and database systems has increased tremendously. To analyze this enormous amount of data, the interdisciplinary field of Knowledge Discovery in Databases (KDD) has emerged. The field of KDD combines disciplines like database systems. To identify individuals, similarity search on feature vectors is applicable, but even the use of adaptable distance measures is not enough to handle objects having an individual level of exactness. The uncertainty in object description appears also in many other advanced database systems like moving object, and sensor database systems, because no exact values to describe the data objects are available.
