Hello,
The entity relationship diagram (ERD) on the Understanding the CRM page is out of date and contains wrong information. For example, it shows a 1:M relationship between companies & deals when it should be a M:M relationship. Additionally, newer object types like Quotes are missing. This is diagram is a valuable tool for developers and should not be neglected.
Thanks,
Chris
@cmadison , thanks!
Brought to the attention of the team 
Just adding my vote on needing this.
Connecting ‘Contacts’ with ‘Contact Lists’ is not clear…
Any status update on this? We’re diagramming our custom objects, and our team’s non-techy people are confused. Would love to build our ERD off of HubSpot’s & simply include our own custom objects/association labels.
It appears that the ERD was updated in March of 2022
@cmadison , have you found a current HubSpot CRM entity relationship diagram? I could not find a complete and current HubSpot ERD, so I made the Best HubSpot ER Diagram yet in Lucidchart at https://lucid.app/lucidchart/6a45d47c-99f2-40f0-a353-dec7dc151d95/edit?viewport_loc=76%2C-1724%2C3274%2C1752%2C0_0&invitationId=inv_4328c2ec-314f-4387-b8fd-aebe0b8898cb.
