2 Development Technology Introduction

2.1 B/S Architecture

The B/S structure is currently the most used structural mode, which can make the development of the system easier, easier to operate, and can also be maintained. When using this structure, you only need to install the database in the computer and some very common browsers. The browser will connect information with the database, which can realize many functions. The B/S structure can be used directly, and the B/S structure greatly reduces the maintenance of work during use. Based on B/S software, all databases are independent of each other, so it is very safe. Because based on the B/S structure, you can clearly see the business being processed by the system, and you can let the managers make decisions in a timely manner, so that you can avoid the loss of the enterprise. The basic feature of the B/S structure is the centralized management mode. After the user uses the system to generate data, the data can be stored in the system database for future use, so that all people's needs can be met.

Figure 2-1 B/S mode three-layer structure diagram

2.2 Java Technology

Java is a cross-platform object-oriented programming language launched by Sun. Because Java technology has the characteristics of excellent versatility, high efficiency, robust security and platform portability, and Java is open source and has the world's largest developer professional community, so Java develops rapidly.

2. 3MySQL Introduction

In software projects, through the database of operational data, it can ensure its security, independence and data consistency, and provide access to the data system, so it can effectively reduce the time for programmers to develop applications.

MySQL can support multi-threading, which can facilitate the use of system resources and improve the speed of operation. And provide odbc, jdbc and tcp/ip to connect to MySQL in various forms; the function is lacking and the scale is small, but it is enough for this system.

Because the source code of MySQL is open to the outside world, anyone can download it through the corresponding method and modify it according to individual needs. MySQL is valued because of its speed, reliability, and adaptability.

Although MySQL may not be very powerful, due to its open source and wide spread, many people are aware of this database.

2.4 MySQL environment configuration

The data of this system uses MySQL, so you need to install MySQL to the specified directory. If you download the non-installed MySQL compressed package, you can directly decompress it to the specified directory. Then click on the file C:\Program Files\MySQL\bin\winMySQLadmin.exe where C:\Program Files\MySQL is the MySQL installation directory. Enter the initial user and password of winMySQLadmin (note: this is not the user and password in MySQL). Don’t worry about filling in whatever you want. After confirmation, a traffic light icon will appear in the task startup bar in the lower right corner. The red light means the service is stopped, and the green light means the service Normal, left click on this icon ->winnt->install the service to install this service, then left click on this icon ->winnt->start the service to start the MySQL service.

Change the root password of the MySQL database. Use cmd to enter the command line mode and enter the following command:

cd C:\Program Files\MySQL\bin

MySQLadmin -u root -p password 123

Press Enter and Enter password: appears , which is to enter the original password. The password was empty when it was first installed, so press Enter directly. At this time, the password of the account root in MySQL is changed to 123 and the installation is complete.

2.5 Spring Boot technology

This technology is an open source application framework of the Java platform, and its purpose is to simplify the initial construction and development process of Spring. By default, many framework usage methods are configured, and Jar packages are automatically loaded, in order to allow users to run spring applications as quickly as possible.

The main advantages of SpringBoot are: 1. Provide a faster and broader entry experience for all Spring development; 2. Zero configuration; 3. Integrate the configuration of a large number of commonly used third-party libraries; 4. Provide ready features. Today, almost all developers in the Java field are using SpringBoot, gradually becoming a leader in the field of development.

3 System Analysis

3.1 Feasibility analysis

Before developing the system, it is necessary to conduct a system feasibility analysis. The purpose is to use the simplest method to solve the biggest problem.

Its friendly interface and powerful functions bring a lot of convenience to program developers. In addition, the environment is simple and easy to transfer, which undoubtedly makes this system the best choice. Therefore, the background design chooses to use the MySQL database mainly for the establishment and maintenance of information. For front-end development, it should have the advantages of complete functions and easy operation, while the background database requires the ability to establish and maintain the unity and integrity of data information.

According to the above objectives, the hardware of this system is analyzed as follows:

Pentium 3 processor;

The memory is 2G;

The hard disk is 50G;

Employees must go to the company to work, and some jobs can also be done at home. This makes people's working efficiency greatly improved. The variety of operations has also become higher. Therefore, computerization and intellectualization of management are an inevitable trend brought about by social development. Various intelligent software emerge in endlessly. Different software can meet different needs of users, which not only improves work efficiency but also completes some customer-specific tasks. need. The interface of this system is not only simple and clear, but users can modify, delete, add and other operations on relevant information as long as they use the mouse and keyboard. Because the operation of this system is very simple and easy to use, for those who use the system for the first time, it only takes a little time to get started. It can be seen that the system is feasible in operation.

3.2 Analysis of System Performance Requirements

Analyze system performance, including system responsiveness, interface simplicity and clarity, storage capacity, ease of learning and stability;

7总结与心得体会

7.1 总结

通过完成该致远汽车租赁和本论文的撰写让我更加明白了软件开发过程中软件工程思想的重要性。在项目的前期由于对需求分析做的不够谨慎和明确,导致了后面在设计甚至编码时候造成了许多不必要的麻烦。由此在今后的学习和工作开发之中必须要牢牢把握住软件工程的设计思想和方法,这样可以进一步保证项目开发的健壮性和准确性。

本网站所实现的是一个致远汽车租赁系统，该系统严格按照需求分析制作相关模块，并利用所学知识尽力完成，但是本人由于学识浅薄，无法真正做到让该程序可以投入市场使用，仅仅简单实现部分功能，希望日后还能改善。

本系统具有以下优点：

该系统具有较高的适用性，选用B/S结构，可以在绝大部分个人平台上使用该系统。

系统将用户权限进行划分，管理员，用户和业务员能看到及操作的信息不一样，三者具备不同的操作权限。

该系统操作界面简单明了，大部分人都可以正常使用。

但也存在以下问题需要改进：

运行时窗口不能被刷新，可以改进。

系统过于简单，显示的信息有限。。

不能添加多个管理员账号，如果可以则将利于发展致远汽车租赁规模，便于致远汽车租赁信息集中管理。

不能实时预约接待消息和致远汽车租赁反馈建议，容易被忽视，不利于管理员服务客户。

7.2 心得体会

由于经验和能力不足，导致在开发、设计该系统的时候，出现了比较多的问题，例如需要用到的技术不熟悉、程序报错等,后来我积极地向同学询问自己出现的问题同时也会找一些相关的书进行学习,慢慢的一点点将自己遇到的问题逐渐解决。所以不管以后在任何时候合作都会让自己事半功倍。通过本系统的完整的开发,可以遇到自己平时写一些简单的小程序遇不到的问题,不仅仅局限与技术与业务方面的,同时也使得自己更加深入的了解软件过程的开发设计思想,对于即将踏入社会工作而言,这些心得都十分重要。在以后的研究生学习生涯也必须加深这方面的理解,将最好的开发技术和最新的科学原理运用到自己以后的开发工作和学习研究中去。

致谢

过程永远比结果重要。毕业设计是大学学习中最为浓墨重彩的一笔，在这个过程中不仅学到更为全面的书本和实践知识，更让我感受到了浓浓的同窗之情及师生情。虽然大学四年间做过不少作业，但是独立完成这样一个操作系统还是第一次，遇到困难时理所当然，我也有所心理准备，但是超出自身能力的部分还是需要寻求教师及同学的帮助。在此，我衷心地感谢我的指导教师，可以说，没有教师我就不能顺利完成这次设计。他总是在一筹莫展的时候为我指引方向。比如在开题报告，我的指导教师就细致地指导我该怎么有逻辑地将自己的想法和做法表达清楚，在此由衷感谢他。在设计的过程中，教师百忙之中也乐于给予我指导，不管多晚给教师发消息，不管是不是上班时间去教师办公室寻求帮助，他总能在第一时间对我施以援手，由于我在设计期间需要离校实习，不能及时到教师办公室检查设计进度，当时已经是晚上6点多，我匆匆赶到办公室时，教师依然在伏案办公，桌上是同学们的中期检查报告，检查完毕业设计后，他又继续查看同学们的中期报告，并督促我及时上交报告。教师给的意见总是一针见血地指出我设计及论文中的不足，并举例详细说明我的改进方法，不得不佩服他的学术水平及教学水平。在我开始着手实现这个设计的时候，通过需求分析及可行性分析对该系统有了较为浅显的认识；但是在我真正开始实现时发现事情并没有这么简单。任何成功都不是一蹴而就的，就算是一个简单的毕业设计也需要日积月累的知识和经验。于是，我便去寻求老师和同学的帮助，这也使得我得以从不同的角度重新考虑我的设计。终于，这个系统在我内心有了雏形。在真正实现这个设计的过程中，学习新知识是必定的，同时那些由于时间关系或者本来就没有掌握牢固的知识也有了进一步巩固的机会。然而最重要的是了解到如何作为一个开发人员，以开发人员的思维来看待软件开发的步骤和方法策略。

本次毕业设计的完成预示着大学时代的句号，在这个设计过程中，我收获到的绝不仅仅是做项目过程中要到的知识，更多的是同窗情谊和师生情谊，最重要的是做任何事情都要具备的认真态度，以及真正职业的思考方式方法。

最后真心祝愿师生们前程似锦！工作顺利，祝母校越办越好！
