Radio Station Data Reporting And Verification System

Under circumstances which information develops, together with thedevelopment of radio technology, higher requirements have been put forwardfor legalization, rule standardization and informational management.Traditional station application forms, recourse forms are stored in forms ofpaper, which is inconvenient for data check, query, statistics, analysis andsecondary processing. A comprehensive, systematic radio stationdeclaration-verification system will be an imperative direction in whichfurther radio management industry develops. According to the unifiedleadership and planning, division of management and the principle ofindividual responsibility, starting from the practical radio management, thesystem is based on a platform of software system, developing a set of appliedbusiness system aiming at radio management.This paper is divided into five parts, expounding the developmentbackground, total design framework, design and implementation process,design process of database and system security mechanisms of thedeclaration-verification system based on the B/S .NET framework.The first chapter introduces the background and the main work of thesystem as well as the task I have taken responsibility for in the entire systemdesign and development process. Then this part gives a brief introduction tothe design and the technology used in the developing process, which includesASP.NET+ADO.NET technology, the three-tier architecture technology,Hi-size software reuse techniques, component technology and theauthentication mechanism of ASP.NET framework. Finally, this part givesspecific introduction on some difficulties and the solution against thesedifficulties during this process of design and development in the system.The second chapter introduces the network topology and distributeddeployment of database structure in the system. It focuses on the realizationof three-tier architecture. Design ideas and implementation process ofcommunication between two tiers are implemented by XML data templateunder the way the system implemented and three-tier architecture. Under thethree-tier architecture, applications consist of Data Storage Tier, BusinessTier and Client Tier. Data Storage Tier consists of a series of data tables and storage process components; almost all access to data is through the processof achieving Storage. Microsoft itself has very good support from Class andInterfaces to the Data Storage Tier, by using ADO.NET data access solutions,system complete the function of Data Storage Tier by ADO.NET directly.Business Tier is used to process input of two types of application forms andtwelve types of resource forms, to analysis, query, and statistic of station data.Design and development of Business Tier is the main focus of this paper. Themajor function of Client Tier is to display the station data and to validatescripts used for input data. Adjacent tiers in the three-tier structurecommunicate by XML data templates customized within C/S platform.The third chapter of this paper describes the design of the databasesystem. This chapter introduces the design process from the conceptualmodel to the logic model of a station. There are two solutions about themany-to-many relationship during multiple (three or more than three)database tables: (1) by adding new tables, to change the many-to-manyrelationship into one-to-many relationship effectively; (2) by merging tables,to reduce three tables to two tables. Then this chapter analyzes the station'sdata structure. There are too many types of data tables; every table has almostthe same data whereas each table has its specific character. So it is difficult tostore the entire data table in a database table. This chapter introduces aredundant storage design. With this design, all field shared by all data sheetsare stored in the public table, and all other fields are combined as theredundant table. Finally, an E-R design is given for resource table datadesign.Part four focuses on the analysis and design process of the system. Afterlisting all of the system modules and my entire task in the system, aiming atthe entire radio sector business processes, a detailed simulation of the entirebusiness operation process is given, followed by the design of sub process ofsub module based on this entire operation process. This chapter focuses onanalysis processes of station inspection, license management, statistics, andquery modules which are completed by myself. The paper intertwinesapplication of component techniques and software reuse techniques duringpractical business design and developing process as well as some facilitateideas. Finally, the paper introduces safety mechanism of the system as achapter, for the sake of demonstrating its importance to the system. As radiomessages relate to nation's security, it's very important how the system couldbe maintained in B/S structure. System has been made an elaborate design inrunning environment, deployment structure of the database; users'authorityto access the system, users'authority to access module and users'authority toaccess the scope of the data; system runs on the internal network of nationalradio departments, which adopts a three-tier network topology anddeployment of the three-tier database. Based on this, the ASP.NETauthentication technology is used to constraint unknown users and force usersto login pages. The system also uses a dual role in the allocation of theprogram: to assign a role to each user, and to allocate each module a listconfiguring access of the roles. The system specially designs a C/S platformdevoted to the maintenance and configuration data needed by the B/S system.The paper also briefly introduces functions of the C/S platform, includingmaintenance of business based dictionary, XML data configuration templatesand configuration module role.Rooted on practical application, the system meets the admissibilityprocess of input and verification, the business needs and plays a solidsupporting role in the business of radio management.
