WooCommerce is easier to understand at first, while Magento is more structured for large catalogs and complex store rules. WooCommerce stores much of its data through WordPress tables, especially posts, users, metadata, and taxonomies. Magento uses a stricter ecommerce schema with many purpose-built tables and an Entity Attribute Value model for products. If you want quick reporting and a simpler mental model, WooCommerce feels friendlier; if you need multi-store control, huge catalogs, and deep product attributes, Magento makes more sense. TLDR: WooCommerce database tables are simpler because they sit on top of WordPress, but that simplicity can turn messy when product and order data pile into metadata tables.
