Introduction to JAVA
JAVA language is currently the most widely used language development program in the software market. It can be used on a variety of platforms, has strong compatibility, is adaptable to most operating systems on the market, will not appear garbled, has better scalability and maintainability, and has the ability to analyze and solve problems. Procedure-oriented programming makes it easier for us to write stronger code.
Compared with other languages, JAVA is relatively simple, more convenient to compile, and has high security and reliability. According to incomplete statistics, more than 20 million people around the world are using it now. JAVA can be used both embedded and independently. JAVA can be roughly divided into two parts, one is the compilation that JAVA is responsible for, and the other is the operation that JAVA is responsible for. JAVA and C++ languages are very similar, but JAVA is compiled in an object-oriented way when programming, so that the compiled software can be used on a stand-alone computer or on the Internet, and it is more convenient to check for errors. The distributed and architecture-neutral characteristics of JAVA also make its storage faster and editing simpler. Object-oriented includes four characteristics. One is encapsulation, which means that certain functions and attributes can be achieved when defining a class. The second is abstraction, which is a type of class. A class with common attributes can be encapsulated in an abstraction to facilitate simple editing. The third is inheritance. As the name suggests, it has the characteristics of the former. Another feature is polymorphism, which can be used in multiple ways together, which shows its good scalability [8].
MYSQL database
The development of the website must be supported by a corresponding database. The database has a certain organizational structure and can store and manage data information. In the past, the function of the database was only data storage and management operations. However, with the changes and development of the times, the current database has evolved into data processing. In this way, the database has gone through many reforms from the initial simple storage of data table information to the current large database that can store thousands of data.
The database used in the university second-hand trading platform developed this time is a MYSQL database. This database runs fast, has high security performance, and has no restrictions on the platform used, so it is widely used in system development. MySQL is an open source and multi-threaded relational management database system. MySQL is an open source database and is cross-platform. Although its functions may not be powerful, many people understand the basic applications of this database. In the database, a total of 10 There are several tables, each of which is corresponding and has its own connection. The database is of great significance. If there is no link to the database, there is no way to run the program. This obviously shows the importance of the database and the program. closely connected [9].
B/S structure
The B/S (browser/server) structure is currently the mainstream network structure model. It can concentrate the core functions of the system on the server, which can help system developers simplify operations and facilitate maintenance and use. Users only need to install current popular browsers such as 360 Browser, Google Chrome, and QQ Browser on the client side, and install databases such as sqlserver and mysql database on the computer [10]. The installed browser interacts with the server-side database for information data. Many things that specialized software can do can also be achieved using the B/S structure model, which can combine Web browser technology, ActiveX technology, and multiple scripting languages. It helps program developers save a lot of development costs. At present, the B/S structure has become the mainstream structure of program development. The best thing about it is that there are no location restrictions and there is no need to install special software. A laptop or computer can access the system if it can access the Internet. Developing the system using B/S will save trouble in later system maintenance. You don’t have to deal with all problems on the server. Simple client-side processing can solve some problems. The developed program will also be more interactive with users. It will also The browser can be refreshed in real time to update local data information of the program.
Feasibility Analysis
At the beginning of system development, system feasibility analysis must be carried out. The purpose of this is to solve the biggest problem with the minimum cost. Once the program development meets the needs of users, the benefits will be many. Next, we will consider whether this system is worth developing from technical, operational and economic aspects.
technical feasibility
The second-hand trading platform of this university uses JSP technology, JAVA programming language and MYSQL database for development and design. As a computer major student, I have been exposed to a lot of knowledge about programming during school, including various programming software. It is also relatively systematic, so I still have a certain degree of confidence in technology development.
