QT Based Contract Management System Server-side’s Research And Application

Contract is the basic basis, economic benefits through strict contract management process, can help enterprises to control the contract costs. Traditional way of the implementation of contract management system has been completed from C/S architecture to B/S structure of the transformation, but the system developer is good at all the work by the Web server to perform, such as some regular tasks, data synchronization and so on, this will lead to a Web server stress, cause server suspended animation.The research status of contract management at home and abroad was reviewed in this paper, the analysis of the current contract management system development theory and technology. Part and gives the requirements analysis, detailed elaborated the income contract and expenses of the business process.Design the architecture of the system, and the main system to use ASP.NET and SQL Server to develop the contract income and expenditure Web part of the contract,the main system architecture diagram is given.In QT technology implements server-side development part, and gives the key implementation code, the server program can be some of the work from a Web server over decoupling, the specific function as follows1. The contract management is realized by using GSM SMS cat technology in the alert function.2. Use the multithreading technology realizes the primary database and cache database synchronization, provide detailed data for contract management.3. Adopt Socket protocol provides external communication interface, convenient mobile phone App access to contract management data.
