In Distributed Database System, data is physically stored across several sites, and each site is typically managed by a DBMS capable of running independent of the other sites. In contrast to parallel databases, the distribution of data is governed by factors such as local ownership and increased...
This implies both shared disks and shared everything. If you think this is too far out, consider this: - Even today there are large distributed systems with SMP nodes who in total run a distributed database system. - In the near future, we will find SMP structures on processor chips, ...

Parallel database systems can exploit distributed database techniques. In particular, database partitioning is somewhat similar to database fragmentation. Essentially, the solutions for transaction management, i.e., distributed concurrency control, reliability, atomicity, and replication, can be reused. ...

早期的DBMS全部运行在单机上,被称之为集中式数据库系统(Centralized Database System)。为了达到数据共享的目的,需要单机上的数据库系统能够连 接起来进行通信和合作,这样产生了分布式数据库系统(Distributed Database System),其中每个单机上的数据库系统具有完备和独立的数据库功能。随着新 硬件技术的发展,多处理机系统...
