查询词典 data storage

Therein, by adopting the ISCSI protocol, the local data storage sub-system constructs the circuital access pattern of the taxation data. The system eliminates the unbalance phenomena between the capability and the demand of the data storage under the traditional bus storage pattern. Under the centralized control pattern, it provides the information access and shares service with the great data volume, the high speed of data transportation and the high availability for the taxation system. By remotely building a backup data center that is totally consistent with the local data center on the IT foundational fabric, the remote data backup sub-system uses the geographical dispersibility of the remote data center and adopts the LVR software replication technology. It implements the synchronous data replication between the local and remote data center, changes the zero standing capability on the great disaster event under the single data center pattern and raises the standing capability on the disaster events for the application and data in the taxation system. By adopting the dynamic replication technology between the heterogeneous data source, the heterogeneous data conformity sub-system successfully shields the various heterogeneous ingredients of the present system.

As shown in figure 2, directory location for "... sales management system data."

在主程序目录内建立名为data的子目录存放改系统数据库文件，为了方便程序调用，要在Dalphi的BDE管理窗口中建立"SPXSGL"的数据库别名，如图2所示，目录位置为"…商品销售管理系统data"。

The input method of multi-scale data and three levels data index are investigated, a new own idea about how to represent multi-scale seamless data is advanced. The viewpoints that seamless GIS is looked on surface of globe reference ellipsoid as spatial information positioning standard and looked on geographic coordinates as reference of spatial data storage are explored, and based on reference ellipsoid surface coordinate, the measurement model of distance, azimuth angle and area are given.(4) The flowchart of data production of seamless GIS is analyzed, on the basis of the program algorithm and the interactive processing of feature adjoining relation, the data production method of seamless GIS is discussed.

研究了无缝GIS多格式、多比例尺空间数据入库的模式，创新性地提出了用数据中间件模式解决GIS多源空间数据无缝集成的新方法，研究了多比例尺数据入库的方法和三级索引机制，并对无缝GIS数据的多尺度表示提出了自己的看法；阐述了无缝GIS以地球椭球面为空间信息定位的参考面、以地理坐标进行空间数据存储的观点，并给出了在椭球坐标系下的距离、方位角和面积度量模型。

For the data-storage of the surface, the data of the Surface, Patch and Vertex have been stored by using the grid-frame formed by three chain-table. So the lookup of the data is easy and the redundancy of the storage is small.

曲面的数据存储，分别用了三个链表形成的网状结构来存储曲面、网格平面片和顶点的数据，这种结构便于数据的查寻，并且存储冗余小。

An example of a data storage media cartridge that is widely employed in removable automated data storage libraries for mass data storage is a magnetic tape cartridge.

在用于海量数据存储的可更换的自动数据存储库内广泛使用的数据存储介质盒的示例是盒式磁带。

Finally, the query processing algorithm based on the load balance data storage method makes all nodes within a ring cooperatively answer the user's query. Although the ring based load balance data storage method and the query processing algorithm consume more energy than the traditional method when answering a user's query, the method makes all nodes within the network consume energy evenly, which avoids the hotspot problem of the traditional method, so the lifetime of sensor networks can be extended.

基于环的负载平衡数据存储协议以及基于此存储协议的查询处理算法虽然在查询处理中所消耗的能量高于传统方法，但可以保证从数据存储到查询处理的整个过程中，网络的所有节点均匀地消耗能量，从而避免了传统方法中的热点问题，达到延长网络寿命的目的。

So in this paper we discuss the content of version management from data storage, and put forward two models of difference storage. Constructing storage threshold unites difference storage and full storage in order to balance space efficiency and time efficiency. It not only improves the answer time of version access but also reduces storage space.

因此本文从数据存储的角度讨论了版本管理的内容，提出两种差值存储模型，构造了版本存储阈值来将差值存储与完整存储相结合，从而有效地在空间效率和时间效率上进行平衡，不仅提高了版本存取的响应时间又减少存储空间。
