云数据库是把各种关系型数据库看成一系列简单的二维表，并基于简化版本的 SQL 或访问对象进行操作的数据库。云数据库能够为多个用户同时提供类似于单节点数据库的服务。在当前云计算技术不断发展中，数据库不断发展进化，从原始的单节点数据库逐渐发展成为云数据库，数据存储能力相对于过去提高了数倍。目前云数据库服务不断增多，在此背景下，讨论了一种云数据库的设计与核心子系统的实现。

Cloud database is a database that regardes all kinds of relational database as a series of simple two-dimensional tables, and conducts operation based on the simplified version of SQL or access object. Cloud database can support service that is similar to the single node database for multiple users at the same time. With the continuous development of Cloud computing , database development is evoluting. From single node to Cloud database, its ability of data storage is multiplied several times. At present, as the increasement of cloud database service, we will discuss about the designing of Cloud database and the implementing of its core subsystem in this paper.
