Abstract:Nutrition and people's daily lives are closely related, related to the health and safety of the masses, related to the healthy development of the national economy and social stability of the overall situation. However, analysis of nutritional information for a long time did not really get the problem, analyze nutrition information is not good, is not only a waste of resources, and to some extent, restricted the improvement of national physical fitness. Therefore, the development of data analysis system designed specifically human nutrition is very important.
This paper follows the system development life cycle approach and structured approach to design and implement a data analysis system for human nutrition. The system is based on C / S mode, using C # language development, database systems, select SQLServer database. The main elements of the system to achieve the nutrition center, data center, user-centered, analytical centers and other functional modules. System is widely used in community service, and improve people's nutrition awareness, knowledge of nutrition universal people, all kinds of people on the diet were evaluated and adjusted to achieve a balanced diet, aim to extend the life of the people's health.
