Magento2 – Understanding Entities in Magento 2

I happened to notice this table.

In case you're still interested, it records the increment_id for order/invoice/shipment of your store.

e.g. Place a new order, it increases by 1.

Set it to 1000000, your next order id will be 1000001.

1. Entity - Entity actually refers to data item. e.g. catalog_category_entity, catalog_product_entity, customer_entity, customer_address_entity
2. Attribute - Attribute refers to the different attributes of an Entity. e.g. entity_type_id.
3. eav_attribute - In this table all attributes for all the entities are stored.
4. eav_entity_attribute - This table contains all the relations between an attribute, its attribute group and attribute set.
