Answer

Hub writes data about artifacts to a designated table in your database. Each column in that table corresponds to an artifact field, and each row corresponds to a state of an artifact.

When a new integration in Hub runs for the first time, it will write to the database the current state of all artifacts in all repository collections that are part of that integration. As the integration continues to run, every time an artifact in a collection is changed, Hub will write a new row to the database capturing the new state of that artifact.
