| The international trade simulating laborator is the very important part of internation trade department for GuangZhou International Eonomic College. As per request,It is quite necessary to design a proper software system for experiment.This paper describe a completed solution by deeply investigating and researching base on the actual project and others'achievement. The designing process of this software system strictly complying with the software engineering norm.This paper introduce the background of this project firstly and then state the project's construction target, construction principle. The UML technology is used during the demand analysis phase.Then the paper indicate the technical environment,network environment, designing principle, also specific that the system adopt 3 layer structure as express layer,transaction layer and data layer.The developing tool is Visual Studio 2008(ASP.NET 3.5, C# language) together with current popular WED developing technology including HTML, CSS, JavaScript AJAX etc .The software system run in windows XP environment. The DBMS is developed by SQL Server 2005.The main function of the software was introduced breifly. Some detail code and technology to realize the function was given in the paper. I also state how to proceed testing in order to reduce the error to lowest level. Finally I point out the shortcut of this system and what should I do in the future. |
