How to use Java to develop the member discount management function of the ordering system

Abstract: With the popularity of the Internet and the development of technology, the ordering system has become an important part of many restaurants essential tool. In order to improve users' shopping experience and increase user stickiness, many restaurants will also launch membership systems and attract users through member discounts. This article will introduce how to use Java to develop the member discount management function of an ordering system to help restaurants better manage member discounts. Including the calculation of member discounts, management of discount information and interaction with the database.

Keywords: ordering system, member discount, Java development, management function

1. Introduction
As the competition in the catering industry becomes increasingly fierce, restaurants need to provide better services and More attractive offers to attract customers. Membership system and member discounts have become one of the methods widely used by various restaurants. By developing a member discount management function for the ordering system, restaurants can better manage member discounts and improve members' purchasing power and loyalty.

2. Calculation of member discounts
The calculation of member discounts is one of the important functions of the ordering system. Usually membership discounts are calculated based on membership level and discount ratio. In Java development, we can implement the calculation of membership discounts by using object-oriented programming ideas. First, you need to design a membership class that contains the basic information of the member (such as member ID, level, discount ratio, etc.). Then, in the order class of the ordering system, you can add a member discount calculation method to calculate the amount payable based on the member information and order amount. Through features such as encapsulation and inheritance, simple and scalable membership discount calculation functions can be implemented.

3. Management of discount information
In order to facilitate the restaurant to manage member discounts, a discount information management function can be developed. This function can include operations such as adding, modifying, deleting and querying discount information. In Java development, you can use graphical interfaces and databases to manage discount information. First, you can design a discount information class that contains basic information about the discount (such as discount ID, applicable membership level, discount ratio, etc.). Then, the graphical discount information management interface is implemented by using Java Swing components and event listeners. At the same time, a database can be used to store discount information, and interaction with the database can be implemented through Java JDBC.

4. Interaction with the database
For the member discount management function of the ordering system, interaction with the database is essential. Through interaction with the database, persistent storage and query of discount information can be achieved. In Java development, JDBC technology can be used to connect and operate with the database. First, you need to configure the connection information of the database, including the database URL, user name and password, etc. Then, you can use Java's JDBC API to implement the database's addition, deletion, modification, and query functions. Through technologies such as encapsulation and exception handling, stable and reliable interaction with the database can be achieved.

5. Summary
This article introduces how to use Java to develop the member discount management function of an ordering system. By designing the calculation function of member discounts, the management function of discount information and the interaction function with the database, it can help restaurants better manage member discounts. At the same time, through the application of Java's object-oriented programming ideas and database technology, functional modularization and persistent data storage can be achieved. Through continuous optimization and updating, the member discount management function of the ordering system can provide restaurants with more efficient and convenient services and improve users' purchasing power and loyalty.

In-depth analysis of the implementation principle of database connection pool in Java development. In Java development, database connection is a very common requirement. Whenever we need to interact with the database, we need to create a database connection and then close it after performing the operation. However, frequently creating and closing database connections has a significant impact on performance and resources. In order to solve this problem, the concept of database connection pool was introduced. The database connection pool is a caching mechanism for database connections. It creates a certain number of database connections in advance and
