Best explanation I found so far. Simple, right to the point is what I love.

I want to say thank you so much. I've been struggling to understand DTOs and why they're so useful. This video has helped me fully understand it and why I should want to implement this.

After hours of searching to understand DTOs, I don't get the point of using it and finally I found this amazing explanation.
So understandable and clear 💯

I know exactly what you mean! So much has changed over the years since I went to school in 2012-2015. Companies have been bought out, SO MANY java updates/versions. It's a lot to catch up on

After watching many videos on this topic, your explanation has been the best: to the point, clear, visual, and with great examples. Question: If you're using an ORM that gives you the option to hide/select the fields you want when data is returned from the database, can you ignore having the DTO and only stick with your model/domain objects for simplicity/less maintenance? Or does that approach tightly couple my business rules to a particular db implementation? Thank you!

[@shadsluiter]

You are correct. The ORM probably gives you the option for creating visible options for each property. I would consider the DTO to be in the services layer.

This is like a graph in GraphQL! As someone coming from a React/node
