经济的发展带动科技的进步，科技的进步影响着人们的生活。科技信息化的发展应用在生活当中的各个领域，这些科技的
赋能正在改变着生活的方式。生活水平的提高越来越多的人们喜欢自驾游旅行，最早人们的出行全是依靠司机对于路况的熟悉
程序来决定路上行走的时间。至从有了导航以后，旅行者们可以实时了解到自己所要达到目的地的路况，还能够根据算法进行
推荐，这些真可谓是科技的力量。在电商模式发展以前，人们只能够通过线下商超的方式进行购物，购物的种类及品质都受到
一定程度的约束，至从电商+供应链模式的兴起越来越多的消费者可以足不出门，通过移动设备下单即可完成全国各地的商品乃
至生鲜下单，真正做到将商品销往全国，这便是改变人们生活方式的信息化力量。此次我们所设计的课题也是如此，随着信息
技术的迅猛发展，计算机散件市场日益繁荣，然而，传统的报价方式在信息透明度、实时性以及交互性方面存在诸多不足。为
了提升计算机散件报价的效率和准确性利用信息化的效率高、准确等优点来解决我们的实际问题。
此次开发所使用的语言是当下主流的Java技术，Java技术不仅功能强大还拥有完整的生态体系，无论是从前端界面的构建
和实现还是从数据库的交互与处理都有着非常成熟的方案。此次我们选择的关系型数据库为MySQL数据库，它的体积小且易上手
能够帮助开发者在数据库的逻辑实现和物理实现上提供更大的支持。

Abstract
The development of economy drives the progress of science and technology, and the progress of science and
technology affects people's life. The development of technology and information technology is applied to all
areas of life, and the empowerment of these technologies is changing the way of life. The improvement of living
standards More and more people like self-driving travel, the earliest people's travel is to rely on the
driver's familiar with the road conditions to determine the road walking time. After the navigation, travelers
can know the road conditions to reach their destinations in real time, and can also recommend them according to
the algorithm, which is really the power of technology. Before the development of the e-commerce model, people
could only shop through offline supermarkets, and the types and quality of shopping were constrained to a
certain extent. With the rise of the e-commerce + supply chain model, more and more consumers could place
orders across the country and even place fresh orders through mobile devices without going out, truly selling
goods to the whole country. This is the information power that changes the way people live. With the rapid
development of information technology, the computer spare parts market is booming day by day. However, the
traditional quotation method has many shortcomings in information transparency, real-time and interactivity. In
order to improve the efficiency and accuracy of computer spare parts quotation, the advantages of high
efficiency and accuracy of information technology are used to solve our practical problems.
The language used in this development is the mainstream Java technology. Java technology is not only
powerful, but also has a complete ecosystem. It has a very mature scheme from the construction and
implementation of the front-end interface to the interaction and processing of the database. The relational
database we choose this time is MySQL database, which is small and easy to use and can help developers provide
greater support for the logical and physical implementation of the database.
