Chapter One Introduction

1.1 Background of system development

During the epidemic, many places experienced a shortage of supplies due to the sudden outbreak of the epidemic. At this time, a large amount of supplies must be deployed and transported to areas with severe epidemics, so that the use of these supplies can help local people ensure the most basic needs. survival requirements, etc. If the use of means of production is improperly managed, or if major or decision-making errors occur during the distribution of means of production, it will directly cause significant economic losses to the wealth of the entire country and the wealth of ordinary people. Therefore, although people have gained a lot of experience in dealing with epidemic outbreaks, they still cannot completely prevent the infection and mutation of the epidemic. In order to cause minimal harm to human beings and the scientific and reasonable allocation of materials has become a A current hot research issue.

Nowadays, most enterprises still use the most traditional management method for material allocation, that is, through EXCEL addition, deletion and modification records. However, this method has many disadvantages. For example, the updated information of material status cannot be fed back to other parts of the company in a timely manner. Colleagues, when operating data, it is easy for the information to be incomplete, unreasonable, right or wrong, easy to be lost, etc. When the data becomes more complex, it will make the work more cumbersome and error-prone.

If the number of materials that need to be tracked and managed is not large, using traditional EXCEL to manage can basically meet the requirements. If material assets account for a considerable proportion of the company's tangible assets, or the stability of the company's management operations needs to be improved, it is Regulations on operating authority, etc. For these enterprises, material dispatch management is particularly critical, which requires the establishment of an internal management system to effectively control these materials.

1.2 Research status

(1) Domestic research status

Domestic management systems sprouted in the 1980s. At that time, our country's computer science lagged behind foreign countries, and we could only refer to and learn from foreign technologies. After inheriting the advantages of foreign systems and combining them with specific domestic conditions, the management system was truly applied in domestic enterprises in the early 1990s and has achieved great development in the past 20 years. After the outbreak of the epidemic, our country immediately prioritized epidemic prevention and anti-epidemic work. Thanks to the mature epidemic prevention system, the development of my country's epidemic material management system started very early, and public bidding began in July 2020. Due to the short development time, the existing epidemic material management system is not mature enough and is not much different from the original material management system. The system's function of connecting with medical staff is not perfect enough, making it inconvenient for medical staff to manage quarantined personnel and failing to meet the real needs of users. Therefore, the existing epidemic material management system still needs to be improved.

(2) Current status of foreign research

Now, 90% of the financial and accounting work in the United States is done by computers, 80%-100% of material information processing is carried out through computers, and the success rate of planning is 80%-90%. In the rapidly developing computer field, 80% of companies use computers for material management, 8% for technical computers, and 12% for manufacturing processes. It can be seen that in computer software, material management is an important field.

Foreign management systems appeared very early. As early as 1963, computer technology was applied to the management of materials and other facilities, and it basically took shape in the 1980s. However, because in the early stages of the outbreak, foreign countries did not pay enough attention to the new coronavirus and did not have a mature epidemic prevention system. The development and development of foreign epidemic material management systems lagged behind China.

1.3 Summary of this chapter

This chapter mainly provides a general description of the development background of the material allocation and distribution management system during the epidemic, as well as the significance of the research. It also introduces the development environment and technology required by the system, and briefly summarizes the full text so that readers can You can understand the general content of the paper in a short time.

2.3 Bootstrap framework

The front-end website design uses the Bootstrap framework, which is a collection of stacked style sheets (CSS), Java scripts and a series of productized components of HTML. Bootstrap has a grid system that can adjust the page according to the user's screen size so that it performs well in all sizes. It also takes into account CSS modularity and can achieve different visual effects. It is simple and fast to use, which can greatly improve development efficiency. Standardize name definition to facilitate later maintenance.

2.4 Introduction to JSON technology

JSON stands for JavaScript Object Notation, which is JavaScript’s object notation. It is a lightweight text data exchange format, and it is independent of various languages and platforms, such as pup, SSM and other programming languages, all of which support JSON. JSON is also easy to understand, so technicians can quickly get started using it.

2.5 Database used by the system

For any newly developed system application design, the matching installation of the database is required, and the database of the material allocation and distribution management system during the epidemic designed and developed this time is HeidiSQL. Its biggest features are simple operation, reasonable interface design, and very practical functions. Especially for DBAs, it pays great attention to parameter settings and function control during operation. It can view and edit information, create and edit tables, views, files, triggers and manage schedules. Additionally, it is capable of outputting structured big data SQL documents. In addition, it also supports multi-line programming. Although it can save the short-term storage of the CPU, its execution efficiency and security performance are still quite high. More importantly, it is a free database application product that can be used in the system construction and application stages. Save some design costs.

3.4 System maintenance analysis

In recent years, with the rise of the system, more and more stores have begun to develop the system. With the increasing number of systems, system maintenance has become an unavoidable problem. Here is a simple introduction to system maintenance. introduction. System maintenance includes the following aspects of work:

(1) During the maintenance of the system, problems are often encountered, which require corresponding changes in the program. There is basically no way to avoid these problems, so it is necessary to make maximum improvements during each maintenance, otherwise once After problems accumulate, the changes to the program will be relatively large, increasing the dimensionality difficulty and maintenance workload. For example: a common system will encounter erroneous data that does not meet the requirements, then the system will have an error, resulting in the interruption of the entire system. The system has been used by users for a long time, and users will gradually understand the system. Correspondingly, they will feedback some loopholes that we have not discovered, or as social development changes with time, environment, and general trends, users will ask the station to add corresponding demand items. At this stage, some software will need to be repaired.

(2) Database that is updated and maintained in real time: When some operations and requirements change, we need to make a transformation to the current database that occurs simultaneously with the changes in various operations, and we need to make a change to the library. Any time care and maintenance.

(3) Code care and maintenance: As society develops, the environment, and general trends change over time, and the system is used by users for a long time, correspondingly there will be feedback on some loopholes that we have not discovered, and then the code needs to be improved on the original basis. Improve the code, or rewrite it. Generally speaking, running new code is a difficult point in code maintenance, so the system requires professionals to be responsible for code maintenance.
