How to design the hot-selling product table structure of the mall in MySQL?
In a mall system, hot-selling products are usually one of the important factors that attract users' attention and increase sales. When designing a MySQL database, a reasonable hot-selling product table structure is crucial. This article will introduce how to design a MySQL table structure suitable for hot-selling products in the mall, and provide specific code examples.
- Product table (products)
First, we need to create a product table to store information about all products. The table should contain the following fields:
-
id
: Product ID, primary key, used to uniquely identify each product. -
name
: product name, used to display the product name. -
price
: Product price, used to display product prices. -
description
: Product description, used to display product details. -
category_id
: Product category ID, used to associate the product with its category.
The following is an example of SQL code to create a product table:
CREATE TABLE `products` ( `id` INT(11) NOT NULL AUTO_INCREMENT, `name` VARCHAR(255) NOT NULL, `price` DECIMAL(10, 2) NOT NULL, `description` TEXT NOT NULL, `category_id` INT(11) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
- Sales record table (sales_records)
Next, we need to create a sales record table, using To record the sales of each product. The table should contain the following fields:
id
: Sales record ID, primary key, used to uniquely identify each sales record.product_id
: Product ID, foreign key, used to associate the product of this sales record.quantity
: Sales quantity, used to record the sales quantity of this product.date
: Sales date, used to record the date when the sale occurred.
The following is an example of SQL code to create a sales record table:
CREATE TABLE `sales_records` ( `id` INT(11) NOT NULL AUTO_INCREMENT, `product_id` INT(11) NOT NULL, `quantity` INT(11) NOT NULL, `date` DATE NOT NULL, PRIMARY KEY (`id`), FOREIGN KEY (`product_id`) REFERENCES `products`(`id`) ON DELETE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
- Hot-selling product table (hot_products)
Finally, we need to create a hot-selling product table , used to store information about hot-selling products. The table should contain the following fields:
id
: hot-selling product ID, primary key, used to uniquely identify each hot-selling product.product_id
: Product ID, foreign key, used to associate products with this hot-selling product.sales_quantity
: Sales quantity, used to record the sales quantity of this hot-selling product.
The following is a SQL code example to create a hot-selling product table:
CREATE TABLE `hot_products` ( `id` INT(11) NOT NULL AUTO_INCREMENT, `product_id` INT(11) NOT NULL, `sales_quantity` INT(11) NOT NULL, PRIMARY KEY (`id`), FOREIGN KEY (`product_id`) REFERENCES `products`(`id`) ON DELETE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
Through the above table structure design, we can easily record the sales of each product and display the hot-selling product table. Find information about hot-selling products in the best-selling products table. We can sort the best-selling products based on sales quantity and display them to users.
In order to better use the above table structure, we can also create triggers or scheduled tasks to automatically update the sales quantity field in the hot-selling product table. When a new sales record is generated, the trigger or scheduled task will automatically update the sales quantity field to the corresponding value to ensure that the data in the hot-selling product table is always up to date.
In actual development, we can further improve and optimize the above table structure according to business needs. For example, we can add an inventory field to the product table to record the inventory quantity of the product, and add a sales price field to the sales record table to record the price of each sale. This depends on the specific business requirements and system design.

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

Redis uses a single threaded architecture to provide high performance, simplicity, and consistency. It utilizes I/O multiplexing, event loops, non-blocking I/O, and shared memory to improve concurrency, but with limitations of concurrency limitations, single point of failure, and unsuitable for write-intensive workloads.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

Apache connects to a database requires the following steps: Install the database driver. Configure the web.xml file to create a connection pool. Create a JDBC data source and specify the connection settings. Use the JDBC API to access the database from Java code, including getting connections, creating statements, binding parameters, executing queries or updates, and processing results.

The methods for viewing SQL database errors are: 1. View error messages directly; 2. Use SHOW ERRORS and SHOW WARNINGS commands; 3. Access the error log; 4. Use error codes to find the cause of the error; 5. Check the database connection and query syntax; 6. Use debugging tools.

Effective monitoring of Redis databases is critical to maintaining optimal performance, identifying potential bottlenecks, and ensuring overall system reliability. Redis Exporter Service is a powerful utility designed to monitor Redis databases using Prometheus. This tutorial will guide you through the complete setup and configuration of Redis Exporter Service, ensuring you seamlessly build monitoring solutions.
