springboot私人健身与教练预约管理系统源码和论文

随着信息技术和网络技术的飞速发展,人类已进入全新信息化时代,传统管理技术已无法高效,便捷地管理信息。为了迎合时代需求,优化管理效率,各种各样的管理系统应运而生,各行各业相继进入信息管理时代,私人健身与教练预约管理系统就是信息时代变革中的产物之一。

任何系统都要遵循系统设计的基本流程,本系统也不例外,同样需要经过市场调研,需求分析,概要设计,详细设计,编码,测试这些步骤,基于java技术、springboot框架、B/S机构、Mysql数据库设计并实现了私人健身与教练预约管理系统。系统主要包括首页,个人中心,用户管理,教练管理,健身项目管理,项目分类,教练信息管理,教练预约管理,系统管理等功能模块

本文首先介绍了私人健身与教练预约管理技术的发展背景与发展现状,然后遵循软件常规开发流程,首先针对系统选取适用的语言和开发平台,根据需求分析制定模块并设计数据库结构,再根据系统总体功能模块的设计绘制系统的功能模块图,流程图以及E-R图。然后,设计框架并根据设计的框架编写代码以实现系统的各个功能模块。最后,对初步完成的系统进行测试,主要是功能测试、单元测试和性能测试。测试结果表明,该系统能够实现所需的功能,运行状况尚可并无明显缺点

Abstract

With the rapid development of information technology and network technology, human beings have entered a new information age, and traditional management techniques can no longer manage information efficiently and conveniently. In order to meet the needs of the times and optimize management efficiency, various management systems have emerged, and all walks of life have entered the era of information management. Personal fitness and coach reservation management systems are one of the products of the information era.

Any system must follow the basic process of system design, and this system is no exception. It also needs to go through market research, demand analysis, outline design, detailed design, coding, and testing. These steps are based on java technology, springboot framework, B/S organization, Mysql database design and implementation of personal fitness and coach reservation management system. The system mainly includes functional modules such as home page, personal center, user management, coach management, fitness project management, project classification, coach information management, coach appointment management, and system management.

This paper first introduces the development background and development status of personal fitness and coach appointment management technology, and then follows the routine software development process, first selects the appropriate language and development platform for the system, formulates modules and designs database structure according to demand analysis, and then according to the overall system Design of functional modules Draw the functional module diagrams, flow charts and E-R diagrams of the system. Then, design the framework and write code according to the designed framework to realize each functional module of the system. Finally, the preliminary completed system is tested, mainly functional test, unit test and performance test. The test results show that the system can achieve the required functions, and the operating conditions are acceptable without obvious shortcomings.

Key words: Personal fitness and coach appointment management; Springboot; The Mysql database
