What is the best way to interact with the added markers on the map?

Question

Android

Markers from the database are added to Google maps.
When you click on a marker, it is required to display additional information from the database on it.
Interested in what is the best way to link the marker on the map with the data from the database on which it was added?
Searching for the coordinates of the clicked marker in the database is somehow not very beautiful.
