Avoid Inconsistency in Fuzzy Relational Database for Secure Operation
نویسنده
چکیده
Fuzzy relational database handle uncertain and imprecise information for consistent operation on database and manipulate information. In this paper, I introduced fuzzy normal forms for similarity based fuzzy relational database model. First of all I have focused on fuzzy closure of attribute set which can be utilized to find fuzzy key. Next, with the concepts of α -ffd [1], I have defined fuzzy normal forms in fuzzy relational database. I also show some real life application to handle normalization based on α -ffds.

Lossless Join Decomposition Avoid Inconsistency in Fuzzy Relational Database for Perfect Operation
Fuzzy relational database handle imprecise information on database to maintain integrity of operation. Already I handled different normal form to reduce redundancy of data in a database. Decomposition of a relation should not be arbitrary either by tuples or attributes of a relation. In this paper, I have focused on lossless decomposition of third or Boyce Codd normal form based relation so tha...
متن کاملApply 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 کاملON A LOSSY IMAGE COMPRESSION/RECONSTRUCTION METHOD BASED ON FUZZY RELATIONAL EQUATIONS
The pioneer work of image compression/reconstruction based onfuzzy relational equations (ICF) and the related works are introduced. TheICF regards an original image as a fuzzy relation by embedding the brightnesslevel into [0,1]. The compression/reconstruction of ICF correspond to thecomposition/solving inverse problem formulated on fuzzy relational equations.Optimizations of ICF can be consequ...
