Object-Oriented Fuzzy Database Representation through UML

Santosh Kumar, Shweta Dwivedi
2016 International Journal of Computer Applications  
As an uncertainty orvagueness in any database is represented through the fuzzy techniques, an object-oriented database is very efficient in handling that kind of fuzziness and complex database model.  ...  A UML class & Sequence diagram are also designed for representing the complete process of registration and diagnosis of patients and design the fuzzy object-oriented database i.e.  ...  The object-oriented approach is not only used in the programming language but also it is widely used in databases to design object-oriented databases.  ...

Gloria Bordogna, Gabriella Pasi
1999 European Society for Fuzzy Logic and Technology  
In this paper a method is proposed to compute typical objects for the classes in the scheme of a fuzzy object oriented database.  ...  The instances of a class are represented in a topological space and the typical object is derived as "closest" to the fuzzy majority of the class instances.  ...  Last but not least, in Fuzzy Object Oriented data models typical attribute values can be used to support the computation of the partial membership of objects to fuzzy classes [8] .  ...
