Mall SKU inventory management system development guide: Detailed explanation of PHP technology

With the rapid development of e-commerce, more and more companies choose to open online malls and sell products online. For a mall, SKU (Stock Keeping Units) is a very important concept. SKU is a specific code defined by merchants to better manage product inventory. It can uniquely identify a product and record the characteristics and attributes of the product. In order to better manage SKU inventory, merchants need to develop a dedicated SKU inventory management system.

In this article, we will introduce in detail how to use PHP technology to develop a complete SKU inventory management system.

1. System design and planning

Before starting system development, we need to carry out system design and planning. First, the functional requirements of the system need to be clarified, including product management, inventory management, order management, etc. Then you need to design the system database structure and define product tables, SKU tables, order tables, etc. Finally, it is necessary to design the page layout and interaction process of the system to provide a user-friendly operation interface.

2. Database design and creation

1. Product table design

The product table is one of the core data tables of the entire system, which records all products basic information. The fields of the product table include product ID, product name, product category, product description, etc. At the same time, you need to pay attention to setting the product ID as the primary key to ensure the uniqueness of each product.

2. SKU table design

The SKU table is a table that records product inventory information. It has a one-to-many relationship with the product table. One product can correspond to multiple SKUs. The fields of the SKU table include SKU ID, product ID, SKU code, inventory quantity, etc. You need to pay attention to setting the SKU ID and product ID as the joint primary key to ensure the uniqueness of each SKU.

3. Order table design

The order table is a table that records user order information. It has a many-to-many relationship with the SKU table. An order can contain multiple SKUs, and one SKU can also be referenced by multiple orders. The fields of the order table include order ID, user ID, order time, etc.

3. System development

1. Environment setup

First you need to set up a PHP development environment, including installing a PHP parser and configuring a web server (such as Apache) , install database (such as MySQL), etc. Then you need to choose a suitable integrated development environment (IDE) for coding and debugging.

2. Database Operation

Using PHP language for database operations is the core of developing SKU inventory management system. Through PHP's built-in database extensions (such as mysqli, PDO, etc.), you can connect to the database, execute SQL statements, obtain query results, etc. We can write corresponding SQL statements based on the database table definitions during system design to implement operations such as adding, deleting, modifying, and querying the database.

3. Page development

In the SKU inventory management system, page development is a very important part. We need to use front-end technologies such as HTML, CSS and JavaScript to develop a user-friendly operation interface based on the page layout and interaction process during system design. At the same time, it is necessary to interact with the backend, use PHP technology to process requests submitted by users, obtain database data and display it on the page.

4. System testing and launch

After the system development is completed, sufficient testing needs to be carried out, including unit testing, integration testing and system testing. Through testing, ensure that the function and performance of the system can meet the requirements. The system can then be deployed to a production environment and made available to users.

Summary:

This article details the process of developing a SKU inventory management system using PHP technology. From system design and planning, database design and creation, system development to system testing and launch, the specific content of each step is introduced one by one. I hope this article will be helpful to developers in developing the SKU inventory management system in Developer City. As long as you develop according to the steps described in this article, I believe you will be able to develop a powerful, stable and reliable SKU inventory management system. come on!
