基于ssm vue个人需求和地域特色的外卖推荐系统源码和论文

首先,论文一开始便是清楚的论述了系统的研究内容。其次,剖析系统需求分析,弄明白“做什么”,分析包括业务分析和业务流程的分析以及用例分析,更进一步明确系统的需求。然后在明白了系统的需求基础上需要进一步地设计系统,主要包罗软件架构模式、整体功能模块、数据库设计。本项目软件架构选择B/S模式,总体功能模块运用自顶向下的分层思想。再然后就是实现系统并进行代码编写实现功能。论文的最后章节总结一下自己完成本论文和开发本项目的心得和总结。通过外卖系推荐统将会使外卖各个方面的工作效率带来实质性的提升。

Abstract

First of all, the thesis clearly discusses the systematic research content at the very beginning. Secondly, the analysis of system requirements analysis, understand "what to do", including business analysis and business process analysis and use case analysis, further clear system requirements. Then, on the basis of understanding the requirements of the system, we need to further design the system, mainly including software architecture pattern, overall functional modules and database design. The software architecture of the project is B/S mode, and the overall functional modules are layered from top to bottom. Then is the realization of the system and code writing to achieve the function. The last chapter of the paper summarizes the experience and summary of the completion of this paper and the development of this project. Through the delivery system recommendation system will make the delivery of all aspects of work efficiency to bring substantial improvement.

Key words: takeaway recommendation system B/S mode software architecture
