1. Introduction
(1) Background of topic selection
At present, the distribution of the three levels of informatization in my country's retail industry is basically clear: in high-end enterprises, the core structural system of purchase, sale and inventory is basically functioning normally. The main problems faced are deep mining and processing of data and high integration of financial business systems. . Ensure the unity and stability of systems and data based on corporate mergers, acquisitions and reorganization; in mid-range enterprises, decentralized operations are changing to centralized management, and the core structure system of purchase, sale and inventory is changing from decentralized single store management and sales accounting to chain management and purchase price accounting. Transition; in low-end enterprises, which have just set foot in and shifted to the chain retail industry, their understanding of informatization is at a superficial level, and the construction of business processes and information systems requires a period of exploration, understanding and gradual process. The entire retail industry has gradually come to a consensus on informatization: informatization is a necessary means for enterprises to develop sustainably and enhance their core competitiveness. Supermarkets in my country were formed in the early 1990s and have now become an important form of my country's retail industry, playing an important role in the development of the national economy. With the rapid development of supermarkets, their operation and management have become more and more complex. The early salesperson station at the counter can no longer meet the current sales development, so there is an urgent need to introduce new management technologies. The supermarket format has various advantages, but under the current situation, it still has some backward aspects common to retail companies, such as the inability to effectively manage each commodity, slow collection and settlement, prone to business errors, and unsuitable for commodity price adjustments. , Inventory efficiency is low, and in the daily management of supermarkets, decision-making on the purchase, sale, and storage of goods is based on experience and lacks real-time analysis functions. The requirements of managers for timely transmission of data are never met. With the rapid development of Suzhe Supermarket, its operation and management have become more and more complex, the amount of data that needs to be processed daily has gradually increased, and there are more and more intermediate links in business operations. The original manual management can no longer cope with this complexity. market. To this end, during the topic selection process, I chose the topic of supermarket management system design, relying on modern computer information processing technology to manage supermarkets, thus saving a lot of manpower and material resources, improving the working conditions of employees, and reducing labor intensity. And it can quickly reflect the purchase, sales, storage and other status of goods and analyze various feedback information, allowing managers to quickly make corresponding decisions in response to market changes and speed up the efficiency of supermarket operation and management.
(2) The significance of topic selection
Through the development of supermarket management system, staff can perform their own duties. Different users will have certain differences in permissions, and then let them all enter different interfaces, so that you can do your own work alone. , but all the information is in the back-end system, and there will be better management of the entire personnel. Depending on where a person is located, the information they can see is different, but all the information can be summarized together and ultimately play a relevant role. It can make the management of the entire supermarket personnel more convenient and allow everyone to do their job well. After the development of the supermarket management system, it truly has the function of data analysis. It can analyze the products purchased by different members and the corresponding types. At the same time, it can analyze the shipping and purchasing aspects of the supermarket and make statistics on big data. , and also has specific analysis functions that allow us to be well aware of some sales conditions in the entire supermarket, and in the process of selecting sources of goods in the future, we can truly consider the needs of our members and avoid making choices. Those products that no one needs and are not recognized enough can achieve better management and future development of the entire supermarket based on big data and other aspects. In the process of developing the supermarket management system, it is necessary to truly realize the statistical function of daily data, including daily sales volume, and specifically, the remaining goods in the warehouse. These aspects must be counted, and then we will make statistics according to some corresponding After using the data, making comprehensive judgments, and selecting more suitable goods in a timely manner, it will be good for us. The statistical work on daily data allows us to be well aware of the operation of the entire supermarket and the situation of goods in all aspects, and do a good job in management in a scientific and effective way, so that we will have better results. Lots of protection.
