The source of the topic and the significance of the topic

As the distribution center of the whole commodity resources, the warehouse has a wide range of commodities, including managing a large amount of information and data. Most inventory management theories believe that inventory is the sum of all tangible and intangible materials and their values in physical and logical warehouses, including finished products, raw materials, products, work in process, pre-production materials and so on. Although it is necessary to hold some inventory, too much inventory is not only useless but also takes up funds. The occupied funds are very necessary for the company's development and new product development. Reducing capital occupation can also greatly reduce the interest and risk of bank loans. It is more effective to strengthen inventory management for the material inventory with particularly large purchase volume and large fluctuation in the market price of purchased goods. Therefore, it is very important to balance the company's inventory investment and other capital needs. At the same time, the inventory management of enterprises also needs to keep pace with the times.

2 1 century is a century of information explosion. We have changed from industrial age to information age, and inventory management has changed to "timely supply" and "zero inventory", which puts forward new requirements for inventory management concepts and methods. Many enterprises and companies have also established their own local area networks, but the informationization of most companies still stays on the surface hardware, and rarely involves the essence of informationization such as business process reengineering and institutional restructuring. According to the survey, the way of warehouse information management is mainly manual processing of paper media such as texts and forms. For the statistics and verification of goods in and out of the warehouse, manual inspection of account books is often used, and the management authority of managers is not limited, and anyone can check it, which is easy to cause data leakage. In addition, data information processing has a large workload and is prone to errors. Because of the large amount of data, it is easy to lose and difficult to find. Generally speaking, there is a lack of systematic and standardized information management means. Moreover, the general warehousing situation is recorded in the ledger, and the warehouse staff and administrators only remember it clearly at that time. After a long time, if they want to make an inquiry again, they will have to look through a lot of information, which is time-consuming and laborious, and it is even more difficult to change to goods that were long ago. Obviously, it is very necessary to have an inventory management system to standardize, systematize and program the management of goods and improve the speed and accuracy of information processing.

At present, the research and development of this kind of system at home and abroad is also very practical, which can basically meet the basic needs of enterprises. At present, this system is deepening and developing, which can be applied to more enterprises, generally can be applied to the inventory management of various enterprises, but it is not widely used by the public and can only be used by a certain enterprise or unit. In addition, with the continuous development of the network and the expansion of the company's business, customers, suppliers and employees who need to use the inventory management system may be located in different regions, which requires the company's inventory management system to support network management. Web-based inventory management system is adapted to the above needs of customers.
