Chapter 2 System Development Platform and Technology Introduction
2. 1 B/S architecture
The B/S system can be used through a computer with Internet access. Its biggest advantage is that it does not require the installation of special software. First, the browser sends a request to the server, and then the server processes the request and returns the information to the browser. There is no need to access and calculate the data again. It only needs to be responsible for displaying the data to reduce the requirements. If the client is like a "skinny person", the server will become more and more "fat". Compared with the C/S architecture, the biggest difference between the B/S architecture and the C/S architecture is that the application software of the B/S system uses a web browser as a platform for interacting with users, while C/S requires the development of dedicated applications.
There are currently two popular structures in MIS system structures: C/S and B/S.
C/S structure system: The C/S structure is a client server structure. It can assign tasks to the Client and Server sides, making full use of the advantages of the hardware environment at both ends to reduce system communication costs. The main role of the client is to handle human-computer interaction, execute client applications, collect data, and send task requests to the server. The basic function of the server is to execute background programs. It mainly responds to client requests. In addition, its functions also include: sharing management, communication management, file management, etc. of the data service reservation storage system.
B/S structure system: This network structure simplifies the client and concentrates the center of system function implementation on the server. In this mode, only a browser is needed. This structure hands over a lot of work to the WEB server, only requests WEB services through the browser, and then returns information according to the request.
Usually used within the website network, using C/S. The use of B/S is not limited to intranet use. Taking into account a series of requirements of this management system, the system is developed using a B/S structure.
2. 2 Introduction to MySQL
In software projects, by operating the database of data, it can be ensured that its security, independence and data consistency are provided, and access to the data is provided by the system, thus effectively reducing the time for programmers to develop applications.
MySQL can support multi-threading, which can easily use system resources and improve running speed. It also provides odbc, jdbc and tcp/ip to connect to MySQL in various forms; it is lacking in functionality and small in scale, 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 personalized needs. MySQL is valued due to its speed, reliability, and adaptability.
Although MySQL may not be very powerful, many people are aware of this database due to its open source and wide spread.
2. 3 MySQL environment configuration
The data of this system uses MySQL, so MySQL needs to be installed in the specified directory. If you downloaded a non-installation MySQL compressed package, just decompress it directly 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. After confirmation, a traffic light icon will appear in the task launch bar in the lower right corner. The red light means that the service is stopped, and the green light means that the service is stopped. Normally, left-click this icon->winnt->install the service to install the service, then left-click 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
Enter password: appears when you press Enter. This is to enter the original password. The password was empty when it was first installed, so just press Enter. At this time, the password of the account root in MySQL is changed to 123 and the installation is completed.
2. 4 Introduction to Java language
The Java language is a completely object-oriented programming language. The idea of object-oriented programming language is to regard objectively existing things as a class of objects with states and behaviors, and then use abstract methods to find the common states and behaviors of the same class of objects to form a model - a class. Class is the core of Java programming language and the basic abstract unit of Java language. All things in the world are objects, and they can be abstracted into classes with states and behaviors. The main features of the Java language are:
The Java language is typically object-oriented. It provides classes, which in turn provide object models. By using inheritance and polymorphic methods, code reuse can be achieved.
The Java language is safe. The biggest problem to be solved in the contemporary network environment is security. Java has internal security measures to ensure the safety and integrity of the program.
The operation of the Java language is platform independent. Java programs can run on any system as long as the Java operating system is installed.
The Java language is multi-threaded.
The Java language has memory management. Java can automatically manage memory, making good use of system resources and reducing waste.
2.5 Springboot framework
This technology is an open source application framework for the Java platform, and its purpose is to simplify the initial construction and development process of Sping. By default, many framework usage methods are configured, and Jar packages are automatically loaded, in order to allow readers to run spring applications as quickly as possible.
The main advantages of SpinrgBoot are:
- Provides a faster and broader entry experience for all spring development;
- Zero configuration;
- Integrated the configuration of a large number of commonly used third-party libraries;
- Provide ready features. Today, all developers in the Java field are using SpinrgBoot, and it has gradually become a leader in the development field.
