Clean Architecture Android

Here is a great article explaining the difference between a DAO and a Repository. https://www.baeldung.com/java-dao-vs-repository

I would consider the API as an impromptu DAO for remote databases. Since you don't have access to the remote database structure, it will be the closest thing you are going to get to a DAO.

This Repository is responsible for collating the two data sources. The DAO is the local one and the API is the remote one.

It looks like it retrieves the local data and emits it. It then tries to retrieve the remote data to update the local data. It finally then re-emits the local data.

I think the example you posted falls within the normal responsibilities of a Repository, as per the article.
