The database structure of Magento is designed to store and manage various aspects of an e-commerce website, including products, orders, customers, and more.
Understanding the Magento database structure is crucial for developers and administrators working with Magento.
Magento uses the Entity-Attribute-Value (EAV) database model, which allows for flexible and extensible data storage. Here’s a brief overview of key components in the Magento database structure:
core_config_datafor configuration settings and
core_storefor store-related information.
eav_attribute, and tables related to specific entities like
catalog_product_entityfor products and
catalog_product_entitycontains basic product information, while
catalog_product_entity_varcharstores varchar-type attribute values for products.
sales_order_itemstore information related to orders. The structure allows for detailed tracking of each item within an order.
customer_address_entitystore customer-related information. The EAV model is used to accommodate various customer attributes.
catalog_category_product_index, store precomputed values to speed up common queries.
log_visitor. These tables store data related to customer activity, reports, and system logs.
ratingstore information related to product reviews and ratings.
When working with the Magento Framework, developers interact with the database using models. Models in Magento are PHP classes that map to database tables, making it easier to retrieve, update, and manipulate data. The framework also includes a Resource Model layer that abstracts the database interaction, providing a consistent and secure way to perform CRUD (Create, Read, Update, Delete) operations.
The Magento database structure follows the EAV model for flexibility, with dedicated tables for core configuration, catalogue, sales, customer data, and more. The Magento Framework provides models and resource models to interact with the database, making it easier for developers to work with the data within the application.
