What are entities in Magento 2?

Question

Entities in Magento 2 are like:

• Product is an entity?

• Order/Sale is an entity?

• Customer/Users/Clients is an entity?

• etc??

Where can I find a list of all entities? Are they declarated in the DB?

For example in eav_attribute table I can see a column entity_type_id that in a default Magento2 installation goes from 1 to 4, these number represents entities?

PD Taking in mind that eav_entity is empty in a default installation

Answer 1

The eav_attribute table's column entity_type_id is mapped to the eav_entity_type table, you can see the entities there.

Answer 2

Well, englishly speaking, every object is an entity right ?

But I reckon you're referring to an entity as the EAV (Entity - Attribute - Value) implementation of Magento.

So to answer your question, I reckon you should have a look at the eav_entity_type table which lists the following entities with their entity model, table and attribute model:

• 1: Customer
• 2: Customer Address
• 3: Category
• 4: Product
• 5: Order
• 6: Invoice
• 7: Credit Memo
• 8: Shipment

Answer 3

I just notice it (and if it helps to someone)

The table eav_entity_type is where magento2 entities are, for example:

mysql> SELECT entity_type_id, entity_type_code FROM eav_entity_type;
+----------------+------------------+
| entity_type_id | entity_type_code |
+----------------+------------------+
|              3 | catalog_category |
|              4 | catalog_product  |
|              7 | creditmemo       |
|              1 | customer         |
|              2 | customer_address |
|              6 | invoice          |
|              5 | order            |
|              8 | shipment         |
