Django-based graduation design of large supermarket management system
summary
With the continuous development of social economy, supermarkets, as an important retail format, have become one of the main places for people's daily shopping. However, the traditional manual management method has many disadvantages, such as low efficiency and inaccurate information, which cannot meet the needs of modern management.
In order to improve the management level and service quality of supermarkets, it is necessary to develop an efficient and intelligent supermarket management system. As a popular programming language, Python has the advantages of being simple and easy to learn, strong openness, and supports a variety of libraries, and has been widely used. Therefore, the development of a supermarket management system based on Python has become a feasible solution.
I choose to use Python for development because python is really convenient, it can be realized without typing too much code, and it can be used flexibly in many applications, including a series of very successful applications in the direction of web development , At the same time, in order to facilitate development and improve development efficiency, a series of development frameworks have emerged. Django is a very good framework, because many things in the djangok framework have already been configured, so it can help us quickly. A system application is built, such as templates, data processing, website development, etc., so that we can complete most of the development tasks with only Django.
Key words

2.4 Evaluation of references
After reading it, it was of great help to the project development of my graduation project. The author's management of the departure goods and logistics was a great inspiration for me to make a smart supermarket management system.
3. Design concept
3.1 Introduction to development tools
The development of the smart supermarket management system is completed on the Windows system, using Python and django to complete the development. After the development is completed, the project can run in any development environment. The tools we used for this development are IDEA, MySQL and Vision, which are briefly introduced below.
idea is an excellent programming tool that enables efficient and flexible code editing to meet various needs. It not only provides sufficient support for advanced features like Django, but also can greatly speed up your development efficiency.
lMySQL is a relational database used in the research and development of engineering projects. It is small, open, free, easy to learn and install, and is favored by developers. It is the first choice for most online businesses. We store consolidated usage data in this database, which is then programmatically read and displayed on the website.
Vision, one of the Office components, can be used to draw corresponding graphics after installation, which helps us better understand the system and have a clear understanding of the system. It is the most widely used modeling tool in programming.
3.2 Development Technology Introduction
Python is powerful and versatile, including many very successful web development applications. Overloading, templating, data manipulation, etc. It can help us solve many development problems, such as:
The MySQL relational database can effectively improve the efficiency and flexibility of the management system. It can store a large amount of data in multiple tables instead of storing it in a large memory separately, so that data access can be realized more effectively. The SQL language used by MySQL is the most common standard programming language used by database systems, which can meet the needs of various application scenarios. The MySQL software system has been double-certified and is divided into community edition and commercial edition. Its small size, fast operation, low overall cost of ownership, especially its open source features make it an ideal database system for small websites and the first choice for medium-sized development sites.

4.6 Functional module design of smart supermarket
It is designed for the main addition, deletion, modification, viewing, query, and screening of the system, and the functional modules are designed according to these main operations, which greatly facilitates management.
5. Solution to the problem
5.1 Addressing needs identification
Software requirements analysis is an integral part of the software life cycle, which aims to determine the requirements of the project and break them down into more details. This process requires a continuous and in-depth understanding of capabilities and performance in order to optimize and decompose requirements to achieve the best results. During the software planning phase, in-depth analysis of well-defined phases is required to identify and find effective solutions, so that the performance of the software can be continuously improved, which can determine the success or failure of the project and software product. Therefore, the software must be strictly checked, checked, and good methods must be adopted.
在通用信息系统的开发中，规划很重要，提供有关用户需求的描述性信息以供分析。软件设计应该规范不仅是软件开发人员的工作，用户也起着重要的作用。用户需要提前提出对软件的特性和性能的要求，并澄清一些不清楚的地方。软件分析师必须认真了解用户的需求，进行研究分析，最后将用户“how to how”的需求转化为实现模型和详细的软件，具体写出体现用户需求的软件需求。
经过大量研究，确定目标大致为以下三个部分：
u 通用功能：通用功能包括三部分：用户登录、注销、编辑个人信息和更新用户密码。使用系统提供的功能，在用户登录后判断用户身份。
管理基础信息包含：客户信息管理、配送服务控制、产品信息管理、合作伙伴设置、信息管理报警功能，可以实现增删查询。还提供了产品信息列表。
零售业务管理主要是对产品的所有权、售出状况和商品销售统计管理，以确保产品的售出。这些信息可以通过录入、查看、查看历史和统计销售量来实现。那天。
5.2 系统可行性分析
有效性分析包括两个具体方面：可行性分析和创建新系统的可能性。需求在前面的研究中已经详细确定，这里不再赘述。性质、性能和效率。
u技术可行性分析
(1)软件分析
B)Windows操作系统具备人机交互的良好性，它的用户界面简单易懂，而且相关程序也易于使用。此外，还有许多基于Windows的软件开发工具，易于学习、开发和使用。
b) 从可用性来看，MySQL不仅易于使用和掌握，而且能够满足本题的需要，最主要一点免费。
c) django这个系统很完善，有很多书籍和文档可以学习和参考，所以了解这个技术已经不是问题了。
(2) 员工评价
系统简单易用，用户无需拥有基本的商务电脑，系统用户申请本站无任何问题。
u 经济可行性分析
通过财务研究，可以更好地分析组织的业务和投资情况，估算建设和维护的成本。因为这个题目是超市的经营，作者负责作品的开发，所以不需要太多的资金投入，所以也能做生意。
u运营可行性研究
功能能力是指对组织的影响、现有人员和系统现有机构、设施、环境的变化，以及人员额外培训的可能性。现在我们的信息很普及，不同员工的水平都很高，所以他们工作。
6.总结
我做的这个是为提高大型超市管理效率而开发的超市管理系统。具体而言，与现有系统相比，产品注册和销售库存得到了极大改善。这主要系统的开发用是python和MySQL和Django技术。但是由于本系统开发时间较短，对Django框架的理解并不深入。因此，这个系统也存在一些缺陷。由于自己的技术不够，又很多的细节功能自己都没有做出了，比如筛选选择高级查询这些。
