A synchronized design technique for efficient data distribution

作者：

Highlights：

• A heuristic fragmentation and allocation model is developed for performance improvement in DDBS.

• An optimal allocation based on attribute retrieval and update frequency is proposed.

• A change in data access pattern has a negative impact on the allocation process.

• Allocation time is positively correlated with site constraints and fragments replication.

• The number of sites and fragments in DDBSs has a negative effect on allocation time.
