  36. This database schema models various entities and their relationships in an e-commerce or online store application. The relationships between different tables are established using foreign keys, and the primary keys ensure the uniqueness of records within each table. The timestamps (created_at and updated_at) help track the creation and modification times of records.

    Keep in mind that the schema provided here is just a starting point and may need further refinement based on specific application requirements and use cases. Additionally, the schema can be expanded or modified to accommodate new features and functionalities as the application evolves.
