Simultaneous Updation in Mass Data Storage by Using Job Separation in Data Warehouse

V. R. Sofia Chandrasekar, Dr. J.Jagadeesan

Simultaneous update and dynamic scheduling in a data warehouse which the motto of traditional data warehouses. The main motto is to focus on continuous job into mass data storage as data warehouses for pupation of jobs are to minimize the loss of freshness. The skeleton would not be based on the deadline of the incoming jobs. Heterogeneous sources provides the continuous jobs to update in the corresponding their tables in data warehouse. The skeleton scheduling algorithms for updating in mass data storage in the data warehouse. In this proposed work Dynamic Priority Driven Preemptive Scheduling (DPDPS) algorithm is used to assign different priority level at different jobs. DPDPS job separation algorithm shows the tracks to get the jobs for an updating a job and for improving the performance to meet their job completion on time. Equal job separation method provides the jobs into the clusters according to the similar jobs in each track.
