How to design the recommended product table structure of the mall in MySQL?
With the rapid development of e-commerce, mall recommendation systems have become an important means to improve user shopping experience and increase sales. The structural design of the recommended product table in the mall is crucial to the effectiveness and efficiency of the recommendation system. This article will introduce how to design the recommended product table structure of the mall in MySQL and provide specific code examples.
1. Design Principles of Recommended Product Table
Before designing the structure of the recommended product table in the mall, we need to clarify some design principles to provide a better user experience and recommendation accuracy.
2. Recommended product table structure design
In MySQL, a relational database can be used to design and store the recommended product table. The following is a basic recommended product table structure design example:
CREATE TABLE recommendation
(
id
int(11) NOT NULL AUTO_INCREMENT,
user_id
int(11) NOT NULL,
product_id
int(11) NOT NULL,
score
double NOT NULL,
timestamp
timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (id
),
KEY user_id
(user_id
),
KEY product_id
(product_id
),
KEY timestamp
(timestamp
)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
In the above design example, the recommended product table contains the following fields:
3. Storage and operation of the recommended product table
In the mall application, the recommended product table needs to support the storage and operation of data. The following are some common examples of storage and operation operations:
INSERT INTO recommendation
(user_id
,product_id
,score
)
VALUES (1, 1001, 0.8);
SELECT * FROM recommendation
WHERE user_id
= 1;
SELECT * FROM recommendation
WHERE product_id
= 1001;
SELECT * FROM recommendation
ORDER BY score
DESC;
4. Extension of the recommended product table structure
The above recommendations The product table structure is a basic design example, and some fields and indexes can be expanded according to actual needs.
By expanding the structure of the recommended product table, we can better meet different recommendation algorithms and business needs, and provide more accurate and personalized recommended products.
Summary:
This article introduces how to design the recommended product table structure of the mall in MySQL and provides specific code examples. A well-designed recommended product table structure can not only provide efficient data retrieval and operation, but also provide a better user experience and recommendation effect for the mall's recommendation system. By understanding the design principles and flexibly expanding the table structure, a more complex and powerful recommended product table can be designed according to actual needs.
