A Mixed Fragmentation Methodology for Initial Distributed Database Design
We deene mixed fragmentation as a process of simultaneously applying the horizontal and vertical fragmentation on a relation. It can be achieved in one of two ways: by performing horizontal fragmentation followed by vertical fragmentation or by performing vertical fragmentation followed by horizontal fragmentation. The need for mixed fragmentation arises in distributed databases because databas...
متن کاملHorizontal Fragmentation Technique in Distributed Database
Distributed database technology is expected to have a significant impact on data processing in the upcoming years. Today’s business environment has an increasing need for distributed database and Client/server applications as the desire for consistent, scalable, reliable and accessible information is steadily growing. Distributed processing is an effective way to improve reliability and perform...
متن کاملAn Integrated Strategy for Data Fragmentation and Allocation in a Distributed Database Design
A distributed database is structured from global relations, fragmentation and data allocation. A global relation can be divided into fragments and each fragment may itself contain a relation. The fragmentation describes how each fragment of the distributed database is derived from the global relations. The data allocation allows the allocation of discrete sets of fragments to the sites of the c...
متن کاملA New Technique for Database Fragmentation in Distributed Systems
Improving the performance of a database system is one of the key research issues now a day. Distributed processing is an effective way to improve reliability and performance of a database system. Distribution of data is a collection of fragmentation, allocation and replication processes. Previous research works provided fragmentation solution based on empirical data about the type and frequency...
متن کاملSlop based Partitioning for Vertical Fragmentation in Distributed Database System
A Vertical Partitioning is the process of dividing the attributes of a relation. Further, a good Vertical Partitioning puts frequently accessed attributes of the relation together in a fragment. Various researchers have proposed different algorithms for Vertical Partitioning. Still, there is a scope of improvement in previous algorithms for Vertical Partitioning. In this paper a new algorithm i...
