摘要： In executing query distributed processing in a computer system having a plurality of computers, a query and a sliding window are inherited between different computers. If a tuple having a new principal key value is detected when a query is to be executed, a relevant individual query and a relevant sliding window are inherited between computers, and further a sliding window of a relevant common query is inherited between computers.
摘要翻译：在具有多个计算机的计算机系统中执行查询分布式处理时，在不同的计算机之间继承查询和滑动窗口。如果在执行查询时检测到具有新的主键值的元组，则在计算机之间继承相关的单独查询和相关的滑动窗口，并且进一步在计算机之间继承相关通用查询的滑动窗口。

摘要： Disclosed herewith is a terminal for receiving data distributed from a host computer. The terminal includes a database for storing data distributed from the host computer and a schedule manager for managing the schedule of the terminal. Upon receiving an update request for the data stored in the database, the terminal extracts a time band in which the usage frequency of the terminal is kept low as an updatable time through the schedule manager and sends an update request to the host computer in response to the received request. The terminal calculates a processing time required to update object data, as well as a value denoting the usefulness of the object data according to the update information received from the host computer and including the object data, then decides a processing order for the object data according to the processing time and the usefulness value calculated respectively for the object data, thereby updating the data stored in the database according to the decided processing order. Useful data is updated preferentially in the time band in which the usage frequency of the terminal is low.
摘要翻译：这里公开了一种用于接收从主计算机分发的数据的终端。终端包括用于存储从主机分发的数据的数据库和用于管理终端的进度的进度管理器。在接收到对数据库中存储的数据的更新请求时，终端通过调度管理器将终端的使用频率保持为低的时间段提取为可更新时间，并响应于收到的请求。终端计算更新对象数据所需的处理时间，以及表示根据从主计算机接收的更新信息并包含对象数据的对象数据的有用性的值，然后根据对象数据的处理顺序分配给对象数据分别计算的处理时间和有效值，从而根据所决定的处理顺序更新存储在数据库中的数据。在终端的使用频率低的时间段中优先地更新有用的数据。

摘要： A shared-nothing database management system employs a method of adding and removing a database server without significantly affecting the processing performance for accessing a table from a user or an application. A scheduler module creates a schedule which separately handles the addition of a CPU resource and the addition of a storage I/O resource, and a server is added in accordance with the created schedule. A common disk is used to remove a disk at an arbitrary timing. Further, a data region is previously subdivided on the common disk to eliminate a movement of data associated with the addition of a server.

摘要： The present invention aims to dynamically re-configure hosts and storage in a shared-nothing database. In the shared-nothing database, processes 24 to 29 executed in the hosts 11 to 14 access data of a storage device 30. A system manager 70 and a database manager 10 manage the hosts 11 to 14 and the storage device 30. The processes 24 to 29 access one or more disks 51 to 54 of the storage device. To add or reduce the number of the hosts, the processes 24 to 29 are reassigned among the hosts 11 to 14.

摘要： In a storage device, a method is provided for preventing the risk of data loss and a significant decrease of writing speed due to area shrinkage when erased erase blocks have become fewer. A process of allocating a new page includes determining whether the length of a deallocated pages list is longer than n pages. If the list length is longer, one page is allocated from the deallocated pages list. If the list length is shorter, a capacity shortage error returns. Deleting a file using an erased pages list includes determining whether a page to be processed is emptied by deleting the file. If not so, the file is deleted from the page. If so, the contents of the last page-a in occupied pages are copied to the page, the page-a is written with data for erasure, and any erase block included in the page-a is made erasable.
摘要翻译：在存储装置中，提供了一种防止数据丢失的风险的方法，并且当擦除擦除块变得更少时，由于面积缩小而显着降低写入速度。分配新页面的过程包括确定取消分配页面列表的长度是否长于n页。如果列表长度较长，则从取消分配的页面列表中分配一个页面。如果列表长度较短，则容量短缺错误返回。使用删除的页面列表删除文件包括确定要处理的页面是否通过删除文件被清空。如果不是这样，该文件将从页面中删除。如果是这样，被占用页面中的最后一页的内容被复制到页面，页面a被写入用于擦除的数据，并且包含在页面a中的任何擦除块被擦除。
