1)分布式.在网格环境下,可用的存储空间是巨大的,存储的数据是少量的,但它们分别处于不同的系统,组织和策略的管理之下.即使对一个数据集,也可以存放在不同的地方,即在地理上是分布的.
1). Distributed in the grid environment, the available storage space is huge, the stored data is small, but they are in different systems, under the organization and strategy management. Even for a set of data can also be stored in different places, which is geographically distributed.
2)虚拟化.虚拟化是为隐藏数据模型,物理介质,数据管理软件,数据访问接口,本地或远程数据等区别而提供的一个抽象视图,虚拟化是管理和使用网格分布式数据资源的重要概念和方法.
2). Virtualization virtualization is the hidden data model, physical media, data management software, data access interface, an abstract view of local or remote data provided by the difference, virtualization is an important concept and method of management and use of grid distributed data resources.
3)多副本.在网格应用运行过程中,为了提高性能,减少由于通信造成的延迟,需要对数据进行复制,产生同一数据的不同副本.网格数据管理机构需要对这些数据副本进行管理.
3). Multiple copies in the grid application in the process of operation, in order to improve the performance, reduce the communication delay caused by the need to copy the data, produce different copies of the same data. The grid data management institutions need to manage these data copies.
4)支持多种应用.早期的网格主要用于科学计算,它以少量分布式平面文件为主,后来以电子商务为代表的商业应用乃至军事应用成为网格应用的新领域,以数据库为代表的结构化数据成了重要的数据类型,随着网格技术的发展,越来越多的新应用将对网格数据管理提出更多的
4) to support a variety of applications. Early grid is mainly used for scientific computing, it mainly distributed in small flat file, then represented by electronic commerce and commercial application of military applications has become a new field of grid applications, structured data to a database as the representative has become an important data type, with the development of grid technology, more and more new applications more of the grid data management put forward more
