II. Northwest Normal epidemic prevention and control statistical information system development
2.1 Requirements Analysis statements.
Design and development of a line with the requirements epidemic prevention and control information system needs of our school, so that it has the following features:
-
(1) all kinds of school staff and students can gather information about the epidemic;
-
(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 requirements GUI interface (WEB page, APP page can be);
-
(5) additional functions: the timing of completing the alert.
For our team to understand the point of view, needs analysis is the analysis of two customer edge mold can demand its meticulous, viable technology. According to overall demand, we found that the project requires three types of people, the first group of people only have to fill function, the second class can be aggregated to view their range, while the third is a class of people is the equivalent of "all" the people . So in the database we will be all kinds of roles designed for a table, the epidemic information designed for a table, that is, two tables.
On the first function , requiring all students can gather information about the epidemic / faculty. We will be abstracted as the first category, it should be specifically designed to fill out a form containing some personal information about the epidemic and submit it to the background. In addition to viewing should not have to modify (except to fill out the outside) and other functions.
On the second function , requiring two departments responsible for epidemic prevention and control of this epidemic can view the personnel department summary, and capable of multi-attribute combinations query and visualization of statistical functions. This role is what we demand of abstraction of the second class, the class can not be the role of additions and deletions to other functions that can only look at the summary and data visualization, the equivalent of a real-life look at a summary of such personnel role, considering the cover and other phenomena, the role does not have permission to delete the increase.
On the third function , requires school officials to log subsystem, you can browse a list of all persons reporting summary data, the data can be combined filter queries to graphically display each school has students reporting and non-reporting statistics and key statistics epidemic case, the query [export] EXCEL file list. This role is a third role, which in addition to additions and deletions to change search and other functions, but also can export tables and data visualization.
On the fourth function , interactive interface requires a GUI, this is not difficult to achieve, can be varied such as app and web pages to achieve.
On additional functions , this function, my companions and I discussed quite a few times, because a variety of forms, I think this feature is not necessary, from my point of view, if enough attention to something, then the possibility is actually quite forgotten small, and basically everyone has a cell phone, the phone's most basic function is to alarm, set their own alarm clocks to facilitate the developers also reminded himself. And my teammates are considered no one is perfect, or choose to fill in a form to remind personnel. So we conceived a variety of methods, for example, micro-channel has become a popular communications software, to do with the micro-channel public number regularly reminded every day to fill, and so on. Finally, we choose is to use e-mail alert manner, the timing to send the user a reminder to fill.
2.2 software design specification.
2.2.1 software background
The end of December 2019, China Wuhan happen novel coronavirus (2019-nCoV) infected with pneumonia epidemic in order to curb the spread of the epidemic, effectively cut off the transmission of the virus, under the guidance of the central government, government departments at all levels to take a series of prevention and control measures: since 2020, at 10:23 on January Ri Wuhan "closed city", 31 provinces and municipalities have also implemented strict control measures; provinces and cities nationwide to send medical teams to participate in rescue work and Wuhan, Hubei; deployment in the country masks, protective clothing, medicines and other urgently needed medical resources to support Wuhan; to guide and supervise enterprises with production qualification of medical supplies across the country to resume production capacity as soon as possible; directed special financial allocation of funds for disease prevention and control; Wuhan guarantee supplies from other provinces to mobilize people's daily lives.
It is worth mentioning that the Chinese Internet companies played an important role in the governance of social epidemic prevention and control. Tencent, for example, about the response to the outbreak control needs to develop a dozen a product. Where the epidemic online inquiry function, to reduce the mutual cross-infection between patients with fever have an important role in patients at home through the Internet Dr. Xiang Zaixian inquiry, reduces the risk of transmission of the virus or infection; rumor smash for the public to take a rational attitude towards the epidemic the development of great significance. Wuhan travel drops also set up a special team to serve the commuter medical staff, which plays an important role in the implementation of Wuhan traffic control. In addition, the new pneumonia patients diagnosed with stroke query tool, users only need to enter their own time by public transport and trips, you can confirm whether the infection was diagnosed counterparts, ahead of self-isolation and treatment work. In epidemic prevention and control, the Chinese Internet companies not only grow in terms of social responsibility has become increasingly mature.
Collection, statistics and troubleshooting information about the epidemic prevention and control mechanism for effective cooperation, our school has developed a faculty / student epidemic reporting system to report daily by the staff of the epidemic, the epidemic of students reported daily, daily epidemic secondary sector summary table, four statistical reporting epidemic prevention and control subsystems. To achieve the basic situation of our school all categories of personnel, the regions and information gathering activities and track health. Teachers and students access to the system for remote reporting of information by our university enterprise micro-channel service hall.
2.2.2 Software Architecture Design
(1) Design three registration login function, and each level of user limit functions make use of.
(2) system has the registration module, login module, reporting module, query module, export module, reminding module composed of six large pieces.
(3) Interface Design
1) External Interface
User interface: at the interface design, simple, easy to operate principle, projecting important information.
Software and hardware interface: The system has a GUI interface, taking into account the simple, easy to manage, the main hardware interface device is a PC, mouse, keyboard. The software interfaces with the main windows platform as the basic platform.
2) the association between the independent and each other within each module, implemented mainly by calling a method of connecting the various parts.
(4) Data Structure Design
Structural design two tables: a user information table and epidemic information table.
2.2.3 Software Functional Description
-
(1) information may be collected epidemic;
-
(2) each of the two roles can view a summary of the department staff epidemic and provide advanced query features a combination of multi-attribute query and visualization of statistical functions;
-
(3) three roles, you can browse a list of all persons reporting aggregated data, use [] advanced query data can be combined screening system to graphically display the college students have been reporting and non-reporting statistics and key data statistics of the epidemic, [export] can query EXCEL file list;
-
(4) human-machine interface requirements GUI interface (WEB page, APP page can be);
-
(5) furnished reminder timer.
2.3 software
Define user classes (User), declare private variables private serial number (id), the name (username), password (Password), user type (type), and packaging each attribute method: set (), get (), because the properties private, not directly accessible, for example, can not be directly provided on the outside id, the id value may be set by setId method, obtaining getId id value.
Definition information category (virus), declare private variables School (college), class (myclass), reporting date (startdate), name (username), telephone (tel), province (province), city (city), district (areas ), students (ischinesestudent), Wuhan students (iswuhanstudent), Hubei students (ishubeistudent), 14 touch any (is14contact), in Wuhan (isinwuhan), Hubei (isinhubei), back to school today (istodayformother), suspected (islikevirus), diagnosis (isconfirmvirus).
beans class Javabean class, config class configuration, mapper for the dao class, service service groups, each responsible for only a duty, a complete calculation of each method, program logic is simple, the class has a higher readability. When designing an interface, the interface to each allocated a certain proportion of the design methods to reduce code redundancy. And high-level module does not rely on low-level modules.
2.4 The core function code display

2.8 Summary of experience
The two have worked really can bring the effect of 1 + 1> 2 do? For this problem through this cooperation, I think the same thing two people collaborate to make, respectively, than doing it alone is certainly much better effect of. Through this twinning, I think it is more good than harm, there is a presence of his teammates, the equivalent of more than a pair of eyes and a different way of thinking, problem-solving point of view and methods can be diverse, multi-angle of, for example, I and his teammates Some dispute and discussion of the design of additional functions there between. For at their own shortcomings also reflect a good contrast for easy upgrade to make up their own in the future. And developed the project should also be more than one person to be rigorous, some work can also be a division of labor, greatly reducing the burden on the individual. The drawbacks is that the views are not uniform, and the distribution of stylized acting, time inconsistency, and so on.
