A Methodology of Integrating Fuzzy Relational Databases in a Multidatabase System

چکیده
Although signi cant progress has been made in developing multidatabase systems that integrate component databases containing crisp data, little has been reported on integrating fuzzy databases in such systems. In this paper, we investigate the problem of integrating fuzzy relational databases in a multidatabase system. We identify new types of con icts that may occur in schemas and data due to the inclusion of fuzzy relational databases. We propose a methodology that resolves these new types of con icts in a procedural manner. In addition, the methodology puts the resolution of these new con icts into the context of the resolution of other types of con icts. A fuzzy{probabilistic data model is used to facilitate the integration.

Apply Uncertainty in Document-Oriented Database (MongoDB) Using F-XML
As moving to big data world where data is increasing in unstructured way with high velocity, there is a need of data-store to store this bundle amount of data. Traditionally, relational databases are used which are now not compatible to handle this large amount of data, so it is needed to move on to non-relational data-stores. In the current study, we have proposed an extension of the Mongo...

متن کاملDetermining Schema Interdependencies in Object-Oriented Multidatabase Systems
Schema analysis is the process of determining and capturing how individual schema items in diverse databases are related to each other. During this process different types of semantic relationships between schema items in different databases are identified and meaningful cross-links are established. The work presented in this paper concentrates on the issue of determining several types of inter...
متن کاملIntegrating Fuzzy c-Means Clustering with PostgreSQL
Many data sets to be clustered are stored in relational databases. Having a clusterization algorithm implemented in SQL provides easier clusterization inside a relational DBMS than outside with some alternative tools. In this paper we propose Fuzzy c-Means clustering algorithm adapted for PostgreSQL open-source relational DBMS.

In this paper, two sets of sufficient conditions are obtained to ensure the existence and stability of a unique equilibrium point of unforced first-order fuzzy relational dynamical systems by using two different approaches which are both based on the fuzzy relational matrix of the model.In the first approach, the equilibrium point of the system is one of the centers of the related membership fu...
