Code Checklist
| Checklist Item | Analysis |
|---|---|
| Summary section | Code specification uncommitted, function is not fully realized, readability, and security needs to be improved. Format specification recommends a unified code, optimization and security. |
| Design Specification | Comply with design patterns, but there is no useless code, there is not part of the design implementation. Recommendation: system functions as much as possible, remove the extra code. |
| Code Specification | Code specification document is not submitted, the code specifications need to upgrade. |
| DETAILED code portion | Code that implements only the graphical user interface, data tables did not import, can not be queried. Recommendations: need to further modify the code late, hoping to achieve complete functional requirements of the project. |
| efficacy | The code can be compiled normally, no timeout situation |
| readability | Code readability moderate, less comment. Recommendation: increase code comments, unified format. |
| Testability | Recommendation: lack of form data test, the latter may wish to add. |
Hamburger law
We often say that [feedback], but at the time to provide feedback, not completely addicted to the past of vintage sesame rotten millet, for others to do the evaluation, conclusions. This will create a [you are doing a good job, I hate you] emotions. We can adjust the angle, the [feedback], become [feedforward], stressed that [you have not done enough in the past, but we can do better in the future] in the technical team, we still have to focus on feedback [behavior and consequences ] this level, do not rush down to [the habits and motivations], [nature]. unless the situation is very grim, needs to touch the hearts of others, let others brink.
Then come back a piece of bread, covered. This time can be echoed at the beginning, to encourage each other to get the job done.

Task three
demand analysis
December 2019, Wuhan happen novel coronavirus (2019-nCoV) epidemic, to prevent further spread of the epidemic, the Chinese government in 2020 January 23 to Wuhan to take quarantine measures, including Beijing, Shanghai and other 31 provinces and cities have also the implementation of strict control measures.
---- quoted from "China to fight the new coronavirus: the progress and impact."
At present, the epidemic prevention and control work to the most critical stage of Chi Jin. Is accurate and efficient collection and statistical school staff and students new crown pneumonia epidemic prevention and control information, and further consolidate the basis for epidemic prevention and control work, determined to win the campus epidemic prevention and control warfare, organized forces school teachers and students to develop a healthy punch card system.
---- quote from the "Notice on the test run, Northwest Normal University teachers and health punch card system."
School staff, distribution of a wide range of students, making the epidemic data collection complicated, difficult. The system built by reporting platform, data integration, and statistical analysis, to provide a scientific basis for further grasp schools epidemic situation. Data is the blood of the platform, dynamic data is now updated to reflect the vitality of the platform. Users fill in the information system via the client interface, while the back-end database synchronization update, and store it up for statistical analysis. By integrating back-end data, it can be screened investigation, to generate the corresponding chart for optimum visibility of the epidemic data.
Functional Requirements
(1) all kinds of school staff and students can gather disease information;
(2) each of the two departments responsible for epidemic prevention and control work of the department staff can view summary epidemic and provide advanced query features a combination of multi-attribute query and visualization of statistical functions;
(3) prevention and control of a designated person in charge of the school Login "Northwest Normal epidemic prevention and control statistical information" subsystem, you can browse a list of all persons reporting aggregated data, use [] advanced query data can be combined screening system to graphically display each college has students reporting and non-reporting statistics and key data statistics of the epidemic, [export] can query EXCEL file list;
(4) human-machine interface GUI interface requirements;

summary
The twinning great experiment harvest, in my opinion the most important harvest will not learn to deal with their own a lot of knowledge points, followed to complete the task as early as possible, twinning experiment helped me a lot, I believe that many students are also the same, but the difference lies in the different possible above the pre-thinking, and I and my teammates do not seem basic consensus, etc., does not exist, did not appear at the discrepancies and comments may be pre clearer division of labor, each also multi consideration for each other a bit, so this knot compared to single projects to cooperate with us much easier.
Also in the twinning process teammates I learned a lot, my first time I overcame the problem is not in place to control, only to find that changes may be better than planned and more, so everything took the early to prepare, instead of the planned sub-points interlocking, but should retain room for change, so that it can cope.
