【摘要】：信息在现代社会生活中的作用日益重要,现代社会是一个信息高度丰富的社会。随着大量信息系统的建成并投入使用,这些系统在为人们提供越来越多便利的同时也带来了一些问题,信息系统之间的数据难以共享,系统之间的业务协同非常困难,对现有系统进行的一点点修改就可能导致系统的崩溃。为了解决这些问题,人们提出了很多的策略,如建立数据交换平台,在统一的框架下进行信息系统的设计等。数字城市就是采用统一整体框架解决现有问题的有效选择。早期的数字城市系统是采用地理空间数据支持建设的系统,这些系统利用空间数据支持数据的采集、分析、处理等。现在数字城市已经被发展为一个基础的信息架构,用于支持和指导信息系统的建设和运行,因此在数字城市框架下不仅仅会定义系统之间的业务流程的交互,也会严格定义数据标准和数据访问的接口标准,数据中心是数据标准、数据访问接口标准以及数据管理标准的合理选择。本文分析了数据城市框架下数据中心的典型需求,并建设了数据中心的原型系统,用以验证数据共享交换以及对子系统开发的支持。实验证明,在统一框架下建设的子系统能够有效地实现数据的共享和业务的协同。作为数字城市的核心基础,数据中心的内涵和外延应随着数字城市功能演化和性能演化而不断发展,云计算是支持数据中心持续演化的有效途径。
[Abstract]:Information plays an increasingly important role in modern society, which is a highly informative society. With the establishment and use of a large number of information systems, these systems not only provide more and more convenience for people, but also bring some problems. The data between information systems is difficult to share, and the business collaboration between systems is very difficult. A slight change to an existing system can lead to a system crash. In order to solve these problems, many strategies have been put forward, such as establishing data exchange platform and designing information system under the unified framework. Digital city is an effective choice to solve the existing problems with a unified overall framework. The early digital city system was built with geospatial data. These systems used spatial data to support data acquisition, analysis, processing and so on. Now that the digital city has been developed as a basic information architecture to support and guide the construction and operation of information systems, it not only defines the interaction of business processes between systems in the framework of digital city. The data center is the data standard, the data access interface standard and the reasonable choice of the data management standard. In this paper, the typical requirements of data center in the framework of data city are analyzed, and the prototype system of data center is built to verify the data sharing exchange and the support of subsystem development. Experiments show that the subsystem constructed under the unified framework can effectively realize data sharing and business cooperation. As the core foundation of digital city, the connotation and extension of data center should develop with the evolution of function and performance of digital city. Cloud computing is an effective way to support the continuous evolution of data center.
