Design And Implementation Of Labor Insurance Coordination Office Systems Based On MVC

Labor insurance coordination of the construction industry, which provides stablelife for the construction retirees, has the feature of strong policy color, large informationflow, frequent data exchange and long time of data storage. In addition, labor insurancecoordination of the construction industry in our country has some particularity, it isneither same from the foreign labor safeguard system, nor of the domestic labor sectorinsurance system. Therefore, the establishment of office systems conforms toconstruction industry is imperative. With the continuous development of computertechnology, a small part of cities in China established the corresponding informationmanagement systems which are mostly based on traditional C/S structure.This thesis studies the current working status of Shaanxi province constructionindustry labor insurance coordination office, establishs a management informationsystem based on B/S structure which belonges to e-government areas. This system isdivided into internal and external networks, the internal network is responsible forinternal operations of provincial office while the external network is applied to citieslabor insurance coordination office for reporting data. In the design and developmentprocess, we adopt the MVC which enables model, view and controller to be relativelyseparated. The realization of this separation allows the architecture with low coupling,lower life cycle costs, high reusability and applicability, etc. In the programming ofbottom code, all data-ralated operations and integrated authentication are on the modellayer. In this layer,we operate database by LINQ to SQL, it’s a good solution to theproblem of impedance mismatch in object-oriented programming. and compared withSQL,it can discover and correct mistakes in time because it check errors when compilethe code. The view layer is responsible for only the user interface display. Controllerlayer is used as a bridge between model layer and view layer, it displays the dataextraction from model layer to the view layer and saves the data changes that producedin view layer to the model layer.In addition, taking the geographical differences between the provincial office andthe cities into account, this thesis also provides an instant communication solutionswhich is based on Office Communicator. A role is specially defined in the provincialoffice which responsible for the transmission of non-confidential data and communication between the cities and the province. This design approach not onlyensuring the communication needs but also the security.
