However, the distribution of the database or the replication of data items is not sufficient to make the distributed DBMS reliable. A number of protocols need to be implemented within the DBMS to exploit this distribution and replication in order to make operations more reliable.M.Tamerzsu...

Definition A distributed DBMS is a software system that manages a distributed database, which consists of data that are partitioned and/or replicated among interconnected server sites. The primary objective of a distributed DBMS is to hide data distribution so that it appears as one logical databa...
并行DBMS 通常实现完全透明 完全透明对于地理分布式 DBMS 来说是一个糟糕的选择->用户希望控制查询的哪些部分在何处执行 在下文中,我们假设完全透明 2. Query Execution 并行处理对sort和select很有帮助。 Parallel Selection: Parallel Sort: 基本思想是通过某个键的range进行分块,每个小块就给一个处理器再各个击...
实现Centralized Coordinator 的其中一种思路就是构建一个独立的组件负责管理事务,叫 Transaction Processing Monitor,即 TP Monitor。 TP Monitor 与其之下运行的单节点 DBMS 无关,DBMS 无需感知 TP Monitor 的存在。 每次应用在发送事务请求时,需要先通过 TP Monitor 确认事务是否可以执行。
= Parallel DBMS is for: - High Performance - High Availability But both PDB&DDB need to consider the following problems: 1. Data Distribution (Placement & Replicatioin); 2. Query Parallelization(Distributed Evaluation). And also, many parallel system consists of network of workstation, the diff...
Learn about distribution transparency in distributed database management systems (DBMS). Understand its importance and how it enhances data accessibility.
Homogeneous DBMS:分布式数据库里使用同一个数据库软件。这样的话会更好互相操作。 Heterogenous DBMS:分布式数据库里使用不同的数据库软件。那不同的数据库软件提供的接口功能会有差异,会导致一些问题的发生。 Master/slave DBMS:主节点管理分节点。 Peer to Peer DBMS:没有层级,节点并行处理。 1. 并行数据库(介绍...
