Unit 5: Database System Architectures
Databases often need to be distributed across a number of different locations, especially because today's global companies need to be able to access data in multiple locations. While one copy of a database could reside in a location and be accessed remotely, it is often more efficient and reliable to replicate data across servers or to have portions of data on databases that share access across locations. In this unit, we will study distributed databases and related issues.
