Design And Implementation Of The Software Project Budget Management System Based On Silverlight And WCF

As an important control tool for corporate strategy implementation, the cost budgetmanagement carries out a comprehensive budget management for enterprise projectsbased on the direction of the target profit. By providing a comprehensive budgetpreparation, budget tracking and budget analysis, it effectively establishes amanagement control system for the cost, profit and investment performance. Thecorporate management can be changed into the prior budget and things-in-the-controlfrom the after-the-fact. Through the effective planning to reduce business risk, theorganizational and operational activities of the entire enterprises are along the track ofthe budget management in a scientific and rational manner.In order to achieve the purpose of the software design of high cohesion and lowcoupling, the system design ideas take full advantage of the traditional three-tier designideas based on innovative and take full advantage of the development of the B/S modewhile in the development mode advantages. In the system, using WCF RIA servicesinstead of the traditional web service in the service layer, WCF service can encrypttransmitted data when the data transfer, the client invoking WCF services can also beused when the asynchronous operation. Thus, the efficiency of the server dataprocessing is improved. In the data access layer, the ling to Entity technology be used tooperate the data entities package, is used to optimize the traditional three-tier system ofthe ADO.NET access technology, the advantage is on the one hand to avoid SQLstatements injection attacks, at the same time, it will have to deal with the data packageinto entities alleviate the pressure brought front desk frequently accessed databaseserver data processing, and improve the efficiency of the server processing data. Thefuture use of Silverlight technology to achieve cross-platform cross-browser, softwaresupport a variety of operating systems of Microsoft and Apple and IE, Firefox and otherpopular browsers.The system is able to meet the various needs of the project budget management,the personal professional solution can be offered in the system. The main function of thesystem includs personnel management, rights management, base price management and project management as well as data security module. Personnel management to achievethe management of human resources within the system configuration; according to thecompany’s internal need to modify the company’s existing departments, delete, andquery, and can also increase the number of departments based on business needs;according to the requirements of the sector posts can add, modify, delete, and querysome role. Rights management by the level of use of the system user, systeminformation security guarantee. Base price management oriented systems costing pricebased on the source, the base price of the module and critical data needs to be encryptedprocessing, only users with the appropriate permissions can create, view or modify.Project management provide the resource base price, personnel base price, combinedwith the expected cycle project development cost budget. While actual expenditure inthe budget comparison at the end of the project development, as well as the lateYun-dimensional calculation of costs required. System data security system with highconfidentiality, key data such as user information, the resource base price, projectconfiguration information to take encryption protection.
