Online Survey System Design And Implementation Based On SSH

With the progress of technology the development of social productivity has been vigorously. The fierce competition is more obvious in the industry between everywhere especially embodied in the commodity market Any enterprise who want to survive in the competition must timely grasp the dynamics of the market, understanding to the actual detailed of the current market situation, according to its own operating characteristics timely adjust, working out the correct enterprise development strategy and marketing policies, to constantly improve their own competitiveness. According to the principle of mathematical statistics, the questionnaire survey to achieve a certain number of, related to the more accurate statistics, the broader the results more comprehensive.Use the Internet to market research is a very effective way.Compared with traditional paper questionnaire, network questionnaire has more personalized, and the number of Internet users in China is big, the results of the survey is more accurate and straightforward.Data acquisition system that can be set up online questionnaire to collect user feedback information is a useful tool to obtain first-hand survey data.This paper introduces the specific function of online data acquisition system design and implementation.First briefly describes the realization of data investigation related theory and technology, required by the system and the system has carried on the analysis of functional requirements; Then on the basis of requirements analysis, the overall framework design of data acquisition system is introduced in this paper system, the system structure and function design is determined. Including user information stored encrypted,dynamic form generation technology, using Java seriliaze technology to realize the movement and deep copy of the form and use of the interceptor to capture the URL access to insert, the JFreechart implementation issues of statistical charts, using POI technology will answer form the.xls files, using AOP implementation log management, distributed data storage, etc.Finally on various modules of the system test and analysis, by analyzing the test results to evaluate system.After a system for the relevant tests proving that the online survey system described can reach the expected effect to some extent in this article, at the same time satisfy the functional requirements of the system demand analysis.
