【摘要】：近年來,我國政府信息化已有相當(dāng)基礎(chǔ)。一個(gè)顯著標(biāo)志是:各部門建設(shè)起為數(shù)眾多的各類信息系統(tǒng)。然而這些系統(tǒng)之間缺少聯(lián)接和溝通,往往“各自為政”,形成了許多信息“孤島”,導(dǎo)致各種相似系統(tǒng)重復(fù)建設(shè),不僅造成資源和資金上的大量浪費(fèi),也影響了政府的效率和形象。G2G(Government to Government政府間電子政務(wù))數(shù)據(jù)交換平臺正是為解決這一問題而生。此平臺實(shí)現(xiàn)了跨地區(qū)、跨部門、數(shù)據(jù)交換管理高效完善的且符合江西省實(shí)際情況的政務(wù)數(shù)據(jù)交換與共享。筆者主要參與了其中的數(shù)據(jù)管理中心子系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)工作。筆者實(shí)習(xí)期間參與的該子系統(tǒng)的主要工作包括:通過對江西省各主要單位數(shù)據(jù)的實(shí)際情況進(jìn)行調(diào)研分析,完成系統(tǒng)的需求與可行性分析,明確了該子系統(tǒng)的需求;完成了系統(tǒng)的概要設(shè)計(jì),包括架構(gòu)設(shè)計(jì)、功能設(shè)計(jì)、數(shù)據(jù)庫設(shè)計(jì)與相關(guān)的表設(shè)計(jì);詳細(xì)設(shè)計(jì)并實(shí)現(xiàn)之前劃分的功能模塊,之后參與系統(tǒng)的各種測試工作。通過以上的分析和設(shè)計(jì),筆者和團(tuán)隊(duì)確定系統(tǒng)主要包括以下功能模塊:(1)基礎(chǔ)配置:對本中心范圍內(nèi)參與交換的服務(wù)器設(shè)備、數(shù)據(jù)庫等設(shè)備和邏輯節(jié)點(diǎn)的信息和參數(shù)進(jìn)行注冊和管理(啟用、停用、刪除等)、同步等操作。(2)交換業(yè)務(wù)管理:完成交換任務(wù)的配置(添加、刪除等)、調(diào)度及相關(guān)的應(yīng)用域、影子表的管理。任務(wù)來源有兩種渠道:一種是在該子系統(tǒng)手動添加交換任務(wù),一種是根據(jù)“信息資源目錄管理子系統(tǒng)”的訂閱訂單自動生成交換任務(wù)。(3)策略管理:制定策略并通過策略引擎服務(wù)類智能地完成最佳策略的生成及輔助任務(wù)調(diào)度,以完成最佳交換策略方案的生成,并推薦給交換任務(wù)選擇綁定。(4)系統(tǒng)管理:主要包含操作日志查詢、系統(tǒng)參數(shù)等系統(tǒng)輔助功能的管理。系統(tǒng)前臺和后臺采用B/S結(jié)構(gòu)的瀏覽-響應(yīng)設(shè)計(jì),遵循SOA的架構(gòu)風(fēng)格。系統(tǒng)本身通過Web Service產(chǎn)品定義成一個(gè)服務(wù),按省市縣三級中心部署,并通過接入ESB服務(wù)總線與接入總線的其他管理中心和前置系統(tǒng)等子系統(tǒng)互聯(lián)。SOA架構(gòu)有松耦合、伸縮性好、接口平臺無關(guān)性等優(yōu)點(diǎn)非常有利于打破信息孤島,實(shí)現(xiàn)政務(wù)資源的的共享與高效利用。并且本系統(tǒng)設(shè)計(jì)與開發(fā)過程中高度重視系統(tǒng)的操作可行性,整個(gè)系統(tǒng)界面簡潔直觀,各功能模塊風(fēng)格一致,功能名稱定義通俗易懂,采用的Web Service產(chǎn)品Axis2使系統(tǒng)速度更快,更容易部署,ESB總線產(chǎn)品Dubbo框架采用更加靈活的接口管理和路由尋址等系統(tǒng)服務(wù)間連接交互管理功能。本系統(tǒng)已完成預(yù)定功能的實(shí)現(xiàn)及測試,并已成功在各級數(shù)據(jù)中心交付使用,大大提高了本省政務(wù)資源的使用效率。
[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.
