چکیده

In real applications, information is often imprecise and vague. Exact information has become an essential part of modern database applications for making next generation information systems more human friendly. Fuzzy techniques have been widely used to represent such vague information in various database models and theories. Because of the efficiency of object oriented databases in handling complex object, this database model is extensively used in representing and manipulating fuzzy data. However there is less research done in the area modeling of fuzzy object-oriented database. In this paper, a conceptual model has been proposed for fuzzy object-oriented databases using unified modeling language.

Modeling fuzzy information in UML class diagrams and object-oriented database models

Conceptual data modeling has become essential for non-traditional application areas. Some conceptual data models have been proposed as tools for database design and object-oriented database modeling. Information in real-world applications is often vague or ambiguous. Currently, a little research is underway on modeling the imprecision and uncertainty in conceptual data modeling and the conceptu...

Modeling Collections in UML and ORM

Collection types such as sets, bags and arrays have been used as data structures in both traditional and object oriented programming. Although sets were used as record components in early database work, this practice was largely discontinued with the widespread adoption of relational databases. Object-relational and object databases once again allow database designers to embed collections as da...

Extending the UML Concepts to Transform Natural Language Queries with Fuzzy Semantics into SQL

Database applications tend toward getting more versatile and broader to comply with the expansion of various organizations. However, naïve users usually suffer from accessing data arbitrarily by using formal query languages. Therefore, we believe that accessing databases using natural language constructs will become a popular interface in the future. The concept of Object-Oriented modeling make...

A Multi-Formalism Modeling Framework: Formal Definitions, Model Composition and Solution Strategies

In this paper, we present a multi-formalism modeling framework (abbreviated by MFMF) for modeling and simulation. The proposed framework is defined based on the concepts of meta-models and uses object-orientation to overcome the complexities and to enhance the extensibility. The framework can be used as a basis for modeling by various formalisms and to support model composition in a unified man...

Mechanism and Methods of Fuzzy Geographical Object Modeling

Fuzziness is an important aspect of the uncertainties of spatial data. In this paper, the mechanism and methods of spatial modeling for fuzzy geographical objects are focused and the following two issues are resolved: (1) Modeling fuzzy geographical objects; (2) Modeling the relation between two fuzzy geographical objects. In the first issue, fuzzy geographical objects are defined by the novel ...
