Title: (EN) Partitioning Ownership of a database among different database servers to control access to the database
(ZH) 在不同数据库服务器之间划分一个数据库所有权以控制访问数据库
Abstract: front page image
(EN) At least a portion of a database (250) is partioned into ownership groups (230, 232, 234, 236) that are each assigned one or more database servers (208, 210, 212) as owners. The database servers (208, 210, 212) assigned as owners (s208, s210, s121) are treated as the owners of all data items in the ownership group. That is, they are allowed to directly access the data items within the ownership group, while other database servers are not allowed to directly access those data items. A database system includes one or more presistent storage devices (214, 216) having a database (250) stored thereon, and a plurality of database servers (208, 210, 212) executing on a plurality of nodes (202, 204, 206) that directly access the persistent storage devices (214,216). At least a portion of the database (250) is partitioned into a plurality of ownership groups (230, 232, 234, 236) that are each assigned an owner set. Only process executing on database servers that belong to an owner set are allowed to directly access data within the ownership group.
(ZH)

至少一部分数据库(250)被划分成所有权组(230,232,234,236),其中每一个都被指派了一个或多个数据库服务器(208,210,212)作为所有者。指派为所有者(s208,s210,s121)的数据库服务器(208,210,212)被看作是这个所有权组中全部数据项的拥有者。就是说它们被允许在所有权组中直接访问数据项,而其他数据库服务器则不准许直接访问这些数据项。一个数据库系统中包括一个或多个保存了数据库(250)的永久存储设备(214,216),以及运行在多个可以直接访问永久存储设备(214,216)的节点(202,204,206)上的多个数据库服务器(208,210,212)。至少一部分数据库(250)被划分成了多个所有权组(230,232,234,236),其中每个所有权组都被指派了一个所有者集合。只有在归属于一个所有者集合的数据库服务器上运行的进程才准许直接访问这个所有权组内部的数据。
