Chapter 1 Introduction

1.1 Background and significance

System management will also be carried out through computers for overall intelligent operation. The brand mobile phone sales information system involves a lot of management and data storage, such as administrator; homepage, personal center , user management, product classification management , product information Management , system management , order management, users; homepage, personal center, my collection management, order management, front page; product information, news information, mine, jump to the backend, shopping cart, etc. This gives managers the work It brings huge challenges. In the face of a large amount of information, traditional management systems collect detailed information through notes. Later, computers appeared, and computer input software was used to count paper information onto the computer. This kind of The method is relatively traditional, and it is troublesome to obtain statistical data information, and it is also affected by time and space, so a brand mobile phone sales information system was developed for this purpose; it provides users with a convenient management platform for administrators to view and maintain, and can be accessed through It is necessary to edit and maintain product information content; for users , they can view product classification and order information at any time , and administrators can obtain system data information without leaving home, and it can also save users a lot time, so the development of brand mobile phone sales information system brings great convenience to managers, and it also facilitates administrators toInformation is processed.

The brand mobile phone sales information system of this paper mainly involves programs, databases and computer technology. Covering a wide range of knowledge can greatly improve the efficiency of staff .

1.2 Overview of research at home and abroad

With the continuous development of the domestic economic situation, China's Internet has entered a rare period of peak development, which has caused Chinese and foreign capitalists to turn to the Internet market. However, the unreasonable structure, shortage of personnel and the increase in market management needs in many management fields have made more people aware of Internet management.

In today's highly developed information, information management reform has become a more extensive and comprehensive trend. " Brand mobile phone sales information system " is based on Mysql database and implemented on the basis of JSP programming. In order to ensure the sustainable development of China's economy, the information age is increasingly updated. At the same time, with the rapid development of the information society, various management systems are faced with more and more data that need to be processed. How to use a convenient and fast way to enable managers to operate in a vast field? Querying, storing, managing and sharing effective data information in the data ocean has important practical significance for our study, work and life. Therefore, academic circles at home and abroad have conducted in-depth and extensive research on this, and a new research field- brand mobile phone sales information system was born.

1.3 Contents of the study

At present, many people still use traditional paper tools as the main tool for information management, and the application of network technology only plays a supporting role. In terms of awareness of network tools, more traditional office software is still the main tool used by people, while relatively comprehensive and professional information management software is still not understood or recognized by most people. This topic aims to realize various functions of the brand mobile phone sales information system through label classification management and other methods, so as to achieve the management of the brand mobile phone sales information system .

The detailed introduction will be elaborated in the following six chapters:

Chapter 1, Introduction, introduces the background and significance of the research topic selection, the research status, and briefly introduces the chapter content of this article.

Chapter 2: Introduce technical knowledge, develop by introducing key technologies, and introduce intuitively expressed technical knowledge into the system.

Chapter 3 focuses on the analysis of the system. Starting from the strong supply and demand market of the system, the feasibility of system development, system processes, and system performance and functions are discussed.

Chapter 4 introduces the detailed design plan of the system, including system structure design and database design.

Chapter 5, the implementation of system design, demonstrates the structure of the system through a detailed description of the system functional design.

Chapter 6: Overall test of the system to determine whether the system can be run online.

Chapter 2  Research on Key Technologies

2.1 Introduction to JSP technology

JSP technology itself is a scripting language, but its function is very powerful because it can use all JAVA classes. When it is combined with the JavaBeans class, it can separate the display logic and content, which greatly facilitates user needs. JavaBeans can extend JSP technology programs to form new applications, and the JavaBeans code can be reused, so it is easy to maintain the program. JavaBean components have internal interfaces that can help different people access the system. In 1999, Sun Microsystems officially launched JSP technology, which is a dynamic technology based on the entire JAVA system and JavaServlet. It is a universally applicable WEB technology and one of the core technologies of this system design. JSP technology can greatly improve the running speed of WEB pages. This content is combined with scripts and encapsulated by JavaBeans and Servlet components. All scripts are run on the server side. The JSP engine will interpret the application submitted by the client, generate the script program and JSP identifier, and then feed the results back to the browser through the HTML/XML page. Therefore, developers can use JSP technology when designing the format and HTML/XML tags of the final page themselves.

Therefore, combined with the needs of the brand mobile phone sales information system and the implementation of functional modules, it is most appropriate to use JSP technology, and JSP has better scalability. The system functions can be continuously expanded during the later use of the system, making the system more complete. , more convenient to meet user management.

2.2 Introduction to JAVA

Java mainly uses CORBA technology and security model to protect data in Internet applications. It also provides full support for EJB (Enterprise JavaBeans), java servlet API, JSP (java server pages), and XML technology. The JAVA language is an object-oriented language that provides the most basic methods to complete specified tasks. Developers only need to know some concepts to write some applications. Java programs are relatively small and their code can run on small machines. Java is a computer programming language with three main features: encapsulation, inheritance, and polymorphism. It is widely used in enterprise web application development and mobile application development.

The difference between the Java language and general compilers and literal translations is that Java first converts the source code into bytecode and then converts it into an executable file for the JVM, which can run on a variety of different JVMs. Therefore, its cross-platform nature is achieved. While this made Java very slow in its early days, it has improved as Java has developed.

2.3 ECLIPSE development environment

ECLIPSE has extensive support, high compatibility and powerful functions. It is a collection of Eclipse plug-ins. It is generally suitable for JAVA and J2EE system development. It supports JDBC, Hibernate, AJAX, Struts, Java Servlet, Spring, EJB3 and other almost all databases on the market. Link tools and mainstream Eclipse product development tools.

ECLIPSE is a well-known development tool in the industry, and this tool is used in the development process of this platform. ECLIPSE is also called an enterprise-level work platform, which is based on the Eclipse IDE. ECLIPSE can help us with database research and development and the use of J2EE. In addition, it can also improve the system's operational capabilities, which is highlighted in the server integration process. ECLIPSE's functions are quite complete and can provide necessary environmental support for J2EE integration to complete functions such as coding, testing, debugging and publishing. It can support JSP, HTML, SQL, Javascript, Struts, CSS, etc.

2.4 Tomcat server

Tomcat is a lightweight server, so it is not universally applicable to small and medium-sized enterprises. But when programmers need to develop or debug JSP programs, this server is usually the first choice. For a person with only basic computer knowledge, the computer system has a good Apache server and can access HTML pages very well. Although Tomcat is an extension of Apache, they can run independently and the two do not interfere with each other. When configured correctly, the Apache server provides technical support for the running of HTML pages, and Tomcat's task is to run Servle and JSP pages. Tomca also has certain HTML page processing capabilities.

2. 5  MySQL database

Databases are an integral part of the system development process. In terms of WEB applications, MySQL AB has developed a MySQL relational database management system with great advantages. MySQL can store data in different tables, which is very flexible and can also increase the speed of the system in practical applications. Database access is most commonly used in the standard SQL language, and MySQL is used in the SQL language, so it is highly compatible. Database operations are essential, including functions such as adding, deleting, modifying, and querying database tables. Nowadays, databases can be divided into relational databases and non-relational databases. Mysql is a relational database. Mysql database is a small relational database. It has its own characteristics: small size, fast speed, low cost, etc. Mysql Database is currently the most popular open source database.

In WEB application technology, the Mysql database supports different operating system platforms. Although the installation and configuration under different platforms are different, the difference is not very big. There are two installation methods for Mysql on the Windows platform, binary version and installation-free. Version. After installing the Mysql database, you need to start the service process so that the corresponding client can connect to the database. The client can log in to the database through the command line or graphical interface tool.

Chapter 3 System Analysis

3.1 System design goals

The brand mobile phone sales information system is mainly for users to conveniently understand product information , view product classifications and view order information . It is also designed to better allow administrators to better store all data information and provide quick and convenient retrieval functions, and to all aspects of the system. The module is determined through reasonable analysis of many of today's developed systems, taking into account the user 's operability, following the principles of system optimization developed, and after comprehensive investigation and research.

Analysis of the functions to be achieved by the system, for the convenient management of the current network, you can view product information, news information, mine, jump to the backend, shopping cart, etc. according to your own needs. This can not only save the user's time, but also eliminate the need to The traditional method requires inquiry . Due to time constraints of many users , there is no way to go to relevant physical stores to obtain information . It is really difficult to meet the various needs of users . Therefore, the development of brand mobile phone sales information system can not only meet the needs of users , but also improve the efficiency of administrators and reduce the original unnecessary workload.

3.2 System feasibility analysis

The development environment and configuration of the system can be installed by yourself. The system uses JSP development tools and the relatively mature Mysql database to interact with relevant data between system users and administrators. The database is modified and maintained according to technical language and needs. , which can make the system operation more stable and safe, thereby completing the development of the system.

( 1) Hardware feasibility analysis

The design of the brand mobile phone sales information system and information analysis does not have any rigid requirements for the computer used. As long as the computer can be used normally for code writing and page design, it is feasible. The main requirements are for the server and the upload after the platform is built. The server has certain requirements. The server must be selected with relatively high security, and then opening the system must be smooth and cannot be paused for too long; it must be cost-effective and secure.

( 2) Software feasibility analysis

The entire system is developed using cloud computing. The advantages of cloud computing are the scalability of traffic and intelligent adjustment based on traffic, ensuring the security of the system and the timely backup of data information.

Therefore, we conducted a feasibility study from two aspects and it can be seen that there is no problem in the development of the system.

3. 3  System function analysis and description

Chapter   6 System Testing

6.1 Test definition and purpose

Regarding the testing of system implementation, the English name is System TEST, or ST for short. ST is a test that uses various functions of the complete system multiple times, in multiple cases, and in multiple environments. This is a simple description of ST. ST can prove whether the function's requirements for the system are met and whether it is effective.

Regarding the implementation of system development, no matter how hard the development process is, some error messages will appear when the system is running. Therefore, in order to ensure the security of the system, improve the usage of the system and bring a better experience to users, the system must be completed before it is completed . , be sure to conduct a systematic test. No matter how perfect the program is, there will be loopholes, and no matter how careful the technical developer is, there will be oversights, so testing the program is a must-do step. Find problems in the system through system testing, and solve the problem online according to the cause of the problem. If you cannot find a solution to the problem, you can consult the instructor or ask your classmates for help. You must find out the problem, otherwise more problems will occur. mistake. Therefore, it is inevitable that errors will occur in the program. Although system testing is time-consuming and laborious, in order to ensure the long-term use of the system in the later period, system testing must be carried out. After the problem is solved, further testing is required until there are no problems before use.

6. 2 Performance test

After any program is successfully developed, it must pass software testing, which is the prerequisite for ensuring the stable operation of the software. The most important step in testing is performance testing. The content of performance testing is as follows:

(1) There are certain requirements for the speed of the test. The speed must be fast, and the errors in the test must be solved as quickly as possible, and the test must be retested to ensure the safety of the entire system operation.

(2) During system testing, the test plan and test report used in the test should be kept well to facilitate the overall maintenance operations after the later operation of the system.

(3) The clustering phenomenon in the entire process of software testing should be given priority.

(4) For the overall system test, do not use your own thoughts to approve the entire system, but approve the system from a fair perspective, whether it is in line with the integrated application of the system.

6. 3 Test module

The test system is the latest Windows 10 system. By testing the operation of each functional module implemented by the system, we can check whether the permission information corresponding to each user 's functional module can be operated and the data information is updated consistently.

In terms of system testing, we usually use two methods: white box testing and black box testing. White-box testing refers to testing that can verify whether the internal operations of the system can run normally based on the requirements specifications on the premise of understanding the internal workflow of the system; black-box testing refers to testing if all the functions of the system are known. Check whether every function in the system meets normal use.

In order to facilitate users to use the " Brand Mobile Phone Sales Information System " and reduce the occurrence of system testing errors as much as possible, we have conducted corresponding tests on the system.

To test all functional interfaces of the system, to put it simply, we enter some data and submit it, and then we check the feedback of each page to check whether the relevant functions of the page can be fully realized.

6.4 Test results

The result of the test evaluation is that the brand mobile phone sales information system meets all functions in the requirements, handles most error conditions, fixes most errors and passes the test. The basic functions of the brand mobile phone sales information system are feasible, and both the functions in the system and the design of the interface are worthy of promotion.
