The Design And Implementation Of Changchun Community Network Collaboration Office Platform

Changchun Community Online Collaboration System is a governmental office system for the inquiry and usage of public information of communities in Changchun. It is a community information sharing center which integrates the office systems of Health Bureau, Social Security Bureau, Labor Bureau, Civil Affair Bureau, etc. based on information sharing and exchange platform of www. changchun. gov. cn, providing governmental departments with Single Sign-On services. According to the Standardization of e-government project specified in Government Information Resource Exchange System—Index of the Exchange of Information between Government Departments, utilizing this system to integrate individual information from Civil Affair Bureau, Health Bureau, Employment Agency, Health Insurance Center and Social Security Bureau, an individual basic information data base, sharing by governmental departments with different permissions, including each citizen' s basic information, family situation, health condition, employment status, insurance status, education, etc. is built to make statistics and investigation easy and accurate. Leaders at all levels and staff in each department are provided with varied and abundant query and statistical reports helping leaders to manage and make decisions, as well as supporting community administration and healthy development.The main function of Changchun Community Online Collaboration System is data query and public functions (report statistics, information notice, data sheet printing) with data query and data statistics as its main presentation. The data statistical function, which has a human design, using Microsoft Framework 2.0 as development platform and integrating Microsoft SQL Server Reporting Service tightly, builds a system powerful enough to help solve the governmental departments' tough problems on data statistics and analysis.B/S structure: (Browser / Server mode): It is a network structure model developed after the popularity of WEB with WEB browser as main application software for the client-side. This model unifies the client-side, focuses the core of the system function realization on the server and simplifies system development, maintenance and use. The most important advantage of B / S structure is that it can be operated anywhere without installing any specialized software as long as there is a computer with Internet access, thus no maintenance needs being done by the clients. The system can be easily expanded because new accounts can be assigned automatically without human interference after the new clients having applied online, gotten the company' s internal security certification (such as the CA certificate) and assigned user names and passwords by the administrator.The system is divided into foreground and background. The background is the entry system, in which a user login via a browser and fill in relevant information. The system checks the legitimacy of users' input and saves the data into the database, and finally returns the results of the operations to the users, completing the information input. Foreground is the display of the pages end users browse. Parameters are passed from the presentation layer, according to pre-defined display styles, to the application layer, which then interact with the database, and the results are returned to the presentation layer which display the received data with varied styles applying the presentation forms of Web components.The interface of the system includes user interface, external interfaces and internal interface. The user interface completes the often-used operations such as the character strings, files and directories manipulations, and Chinese character code processing and so on. External interface is divided into software interface and external interface. As for the internal interface, the information is transmitted between various modules by means of function calls, parameter transmission, and return values. The structure of specific parameters will be described in the contents of the data structure design. The information transmitted by the interfaces is encapsulated data in the form of parameters or return values between varied modules. Software test aims at discovering errors and has always been an important part of software development as well as one of the major means to ensure the quality of software products. The purpose of this system test is to comprehensively test the functional elements of the system and to verify the system's various functional points are there to achieve their full features. The test ensures the software ready for use, proves that it can function as pre-defined, and determines whether the product meets the requirements of the users or specified in the contract. The results of the test are finally checked and accepted, which means the software can be put in use.In this paper, the specific design and realization process of Changchun Community Online Collaboration System is expounded on the base of the analysis of its implementation techniques, theories and methods. And this is a process which has universal adaptability for developing the distributed Web information management system based on .NET framework. and which arrives at the ultimate goal of information sharing.
