1.3 Research on this article The content of
this topic will be to design and implement a Web system that allows users to enter their own various health data in real time, make simple analysis based on the data to establish a personal health curve, and provide relevant information and knowledge as a learning tool for people. Health knowledge and a platform to better manage your own health.
1.4 Introduction to thesis structure
This thesis records the entire process from early system development research and design to system development, testing and summary.
1. Introduction
This chapter mainly introduces the current social background of the system and the purpose and significance of development, and also explains the corresponding technologies and development tools.
2. Object-oriented system analysis
This chapter mainly conducts feasibility analysis and user demand research on the development system, and performs demand modeling based on user needs. Draw use case diagrams and data flow diagrams according to requirements. Lay the foundation for system design.
3. Object-oriented system design:
Based on user needs, outline the system design, design modules, draw functional module diagrams, design the database, draw database physical model diagrams and explain tables to provide guidance for system implementation.
4. System implementation and testing:
Introduce the function implementation in the system, introduce and display the implemented UI interface at the same time. In addition, the system test is explained.
5. Conclusion
Summarize and summarize the system. In addition, the paper also includes three parts: conclusion, references and acknowledgments. Finally, the full-text table index and full-text figure index are appended.
