I think it's up to us.
Parag Doshi said the following:
Component diagram - I read a lot about the different approaches (tier based, package based etc). Finally, didnt follow any of those. I laid the components in logical tiers (though didnt show the tiers in the diagram). The components were stacked left to right, with the leftmost components being the JSPs, Swing components etc and the right most being the DAO, external system etc.
Has anyone shown the database within the component diagram? It just looks a little strange with a DAO that does not have a database connected to it.
I am not sure if I need to show the database, that all.
Has anyone shown the database on their component diagram?
