PrestaShop 1.7 Database Structure
Here are descriptions of the database tables in PrestaShop v1.7. By default, each table has a prefix of ps_. When installing PrestaShop, there is an option to change this prefix. This allows PrestaShop to be installed multiple times in the same database and helps to prevent table name conflicts with other shopping carts installed in the same database.
The table names are all lowercase and use underscores between words, and include the types of objects in the table. For example, the ps_product table contains all the product information. Tables that end with _lang contain translations for the object. For example, ps_product_lang contains product translations.
When a table links together two types of objects, both objects are included in the table name. For example, ps_category_product links products to categories. The ID of each table starts with id_ followed by the object name. For example, the ID of the ps_product table is id_product.
