Application of Parallelism SQL in Fuzzy Relational Databases

Recently, new applications have emerged that require database management systems with uncertainty capabilities. Many of the existing approaches to modeling uncertainty in database management systems are based on the theory of fuzzy sets. This paper introduces basic parallelism in fuzzy relational databases and its queries. Article describes basic characteristics of fuzzy relational databases and their properties, compares fuzzy logic with Boolean one in connection with fuzzy relational databases. Deal with data classification and form of storage fuzzy data in database systems. Paper describes fuzzy queries and parallelism in queries from view of today's systems and their connection to SQL language and its extension fuzzy SQL. Discuss about pipeline parallelism of query operators and its benefits.
