A New Dynamic Data Fragmentation and Replication Model in DDBMSs. Cost Functions

For globally expanding organizations, applications generate dynamic workflows with frequent changes in database access models (write, read) at different sites. In those situations a dynamic process to solve the requests on the site where were generated is recommended. The innovation consists in the possibility to integrate the three fundamental concepts specific to distributed databases: fragmentation, replication and fragments allocation in a model of an unbalanced dynamic system, completely decentralized and fully automated (the system continuously monitors the database and adjusts itself to the recent workload) which will permit remote read/writes to master replica and will offer high availability and performance boost.
