G2G数据交换平台数据管理中心子系统的设计与实现
发布时间：2018-08-26 06:50
【摘要】：近年来,我国政府信息化已有相当基础。一个显著标志是:各部门建设起为数众多的各类信息系统。然而这些系统之间缺少联接和沟通,往往“各自为政”,形成了许多信息“孤岛”,导致各种相似系统重复建设,不仅造成资源和资金上的大量浪费,也影响了政府的效率和形象。G2G(Government to Government政府间电子政务)数据交换平台正是为解决这一问题而生。此平台实现了跨地区、跨部门、数据交换管理高效完善的且符合江西省实际情况的政务数据交换与共享。笔者主要参与了其中的数据管理中心子系统的设计与实现工作。笔者实习期间参与的该子系统的主要工作包括:通过对江西省各主要单位数据的实际情况进行调研分析,完成系统的需求与可行性分析,明确了该子系统的需求;完成了系统的概要设计,包括架构设计、功能设计、数据库设计与相关的表设计;详细设计并实现之前划分的功能模块,之后参与系统的各种测试工作。通过以上的分析和设计,笔者和团队确定系统主要包括以下功能模块:(1)基础配置:对本中心范围内参与交换的服务器设备、数据库等设备和逻辑节点的信息和参数进行注册和管理(启用、停用、删除等)、同步等操作。(2)交换业务管理:完成交换任务的配置(添加、删除等)、调度及相关的应用域、影子表的管理。任务来源有两种渠道:一种是在该子系统手动添加交换任务,一种是根据“信息资源目录管理子系统”的订阅订单自动生成交换任务。(3)策略管理:制定策略并通过策略引擎服务类智能地完成最佳策略的生成及辅助任务调度,以完成最佳交换策略方案的生成,并推荐给交换任务选择绑定。(4)系统管理:主要包含操作日志查询、系统参数等系统辅助功能的管理。系统前台和后台采用B/S结构的浏览-响应设计,遵循SOA的架构风格。系统本身通过Web Service产品定义成一个服务,按省市县三级中心部署,并通过接入ESB服务总线与接入总线的其他管理中心和前置系统等子系统互联。SOA架构有松耦合、伸缩性好、接口平台无关性等优点非常有利于打破信息孤岛,实现政务资源的的共享与高效利用。并且本系统设计与开发过程中高度重视系统的操作可行性,整个系统界面简洁直观,各功能模块风格一致,功能名称定义通俗易懂,采用的Web Service产品Axis2使系统速度更快,更容易部署,ESB总线产品Dubbo框架采用更加灵活的接口管理和路由寻址等系统服务间连接交互管理功能。本系统已完成预定功能的实现及测试,并已成功在各级数据中心交付使用,大大提高了本省政务资源的使用效率。
[Abstract]:In recent years, our government informatization has been quite basic. A remarkable sign is that various departments have built up a large number of information systems. However, the lack of connection and communication between these systems, which are often "separate", form many "isolated islands" of information, which lead to the repeated construction of similar systems, which not only result in a large waste of resources and funds, It also affects the efficiency and image of the government. G2G (Government to Government intergovernmental e-government) data exchange platform is designed to solve this problem. This platform realizes the administrative data exchange and sharing between regions, departments and departments, which is efficient and perfect and in line with the actual situation of Jiangxi Province. The author mainly participated in the design and implementation of the data management center subsystem. The main work of this subsystem during the practice of the author includes: through the investigation and analysis of the actual data of the main units in Jiangxi Province, the requirements and feasibility analysis of the system are completed, and the requirements of the subsystem are clarified; Completed the outline design of the system, including architecture design, function design, database design and related table design; detailed design and implementation of the previous partition of functional modules, after participating in various testing work of the system. Through the above analysis and design, the author and the team determined that the system mainly includes the following functional modules: (1) basic configuration: for the server equipment participating in the exchange within the center, Database and other devices and logical nodes of information and parameters for registration and management (enabled, deactivated, deleted, etc.), synchronization and other operations. (2) Exchange business management: completion of the switch task configuration (add, delete, etc.), scheduling and related applications, The management of shadow tables There are two sources of tasks: one is to manually add an exchange task to the subsystem, One is to generate the exchange task automatically according to the subscription order of "Information Resource Directory Management Subsystem". (3) Policy management: make policy and intelligently complete the best policy generation and auxiliary task scheduling through the policy engine service class. In order to complete the generation of the best exchange policy scheme, and recommend to the exchange task selection binding. (4) system management: mainly includes the operation log query, system parameters and other system auxiliary functions management. The browser-response design of B / S structure is adopted in the foreground and background of the system. It follows the architecture style of SOA. The system itself is defined as a service by Web Service products, deployed according to the three-level center of provinces, cities and counties, and interconnected with other management centers and front-end subsystems of the access bus via the ESB service bus, which is loosely coupled and scalable. The independence of interface platform is very helpful to break the isolated island of information and realize the sharing and efficient utilization of government resources. In the process of designing and developing the system, we attach great importance to the operation feasibility of the system, the interface of the whole system is simple and intuitive, the style of each function module is the same, the definition of function name is easy to understand, and the Web Service product Axis2 makes the system faster. It is easier to deploy the ESB-bus product Dubbo framework with more flexible interface management, routing addressing and other system services connection interaction management functions. The system has completed the implementation and testing of the predefined functions, and has been successfully delivered in the data center at all levels, greatly improving the efficiency of the use of provincial government resources.
