The effects of parallel processing on update response time in distributed database design

چکیده
Network latency and local update are the most significant components of update response time in a distributed database system. Effectively designed distributed database systems can take advantage of parallel processing to minimize this time. We present a design approach to response time minimization for update transactions in a distributed database. Response time is calculated as the sum of local processing and communication, including transmit time, queuing delays, and network latency. We demonstrate that parallelism has significant impacts on the efficiency of data allocation strategies in the design of high transaction-volume distributed databases.

The new copper processing plant of the Sarcheshmeh copper complex consists of two parallel circuits. After a primary crushing, the ore is sent to a SAG mill, and the product is further ground in a ball mill. The overflow of the hydrocyclones is fed to a flotation circuit that contains 8 rougher tank cells (RCS130), 3 cleaner cells (RCS50), 5 scavenger cells (RCS50), and a flotation column (as r...
متن کاملDesigning Distributed Database Systems for Efficient Operation
Distributed database systems can yield significant cost and performance advantages over centralized systems for geographically distributed organizations. The efficiency of a distributed database depends primarily on the data allocation (data replication and placzment) and the operating strategies (where and how retrieval and update query processing operations are performed). We develop a distri...

The variant execution time of the update operation repair rules in a parallel and distributed environment is highly affected by the way the rules and tables settled in a database in according to whether they were partitioned or not. The wellknown partitioning methods in the database were succeeded to reduce the response time of update operations since they expeditiously execute the update opera...
