数据库规范化实战指南：从1NF到BCNF的工程落地数据库规范化（Normalization）是保障数据一致性与系统可维护性的核心设计原则，其本质在于通过消除函数依赖异常来确立单一事实源。理解函数依赖需聚焦‘值生命周期绑定’而非静态映射，而范式演进实为分层防御体系：1NF确保原子性，2NF阻断部分依赖，3NF切断传递依赖，BCNF则严控决定因素必须为超键。在电商、SaaS及金融等高一致性场景中，规范化直接决定update anomaly能否根治、BI报表是否可信、跨系统数据是否同步。本文基于PostgreSQL/MySQL/SQL Server真实环境，覆盖阅读详情

2. Summary and harvest

Through the prototype development in this course, I have learned some relevant knowledge such as back-end express, mysql and front-end uniapp, and enhanced my communication ability and code level in the communication and collaboration with team members.
At the same time, I also watched the development software used by the team members, such as mysql and hbuild. I learned a lot about the basic steps needed to develop small programs.

2.1 personal programming

For the personal programming( Lab1-1 and Lab1-2 ), I made a brief self-introduction and wrote a section of code about mathematical operation according to the assignment requirements; Download and use github for the first time.

2.2 pair programming

For the pair programming( Lab2-1 and Lab2-2 ),I tried to write complex math operations in the java language code, and wrote a simple cookie running program.

2.3 on-site programming

I understand part of the programming knowledge of making small programs, but also enhance the proficiency of c language

2.4 team project practice experience summary + example

2.5 example combined analysis

We had a lot of difficulties discussing project topics, developing improvements in prototyping techniques, and page design, followed by different programming levels and time differences in message notifications.However, fortunately, we all have more patience and enthusiasm, and collected a lot of information about the development of small assistants for the games in the early stage.
