Thank you Pascal. This is can be more precise than just I looking at the visualisation .
But, for example, what is the “timestamp” in the “node" table? And what is the “redactions” table? Or, why in the “way_nodes” table there is “version", but also it is just a link to the “nodes” table that contains also the “version” attribute. For this reason, I was trying to look to an explanation of this schema if it exists.

I knew how OpenStreetMap works, and I'm contributing by years. I know how the basic database schema works and for this reason I wrote here to understood if someone has more detailed explanation of all the table that I sent in the first mail. My idea was to explain this table, but some names are not so clear. The general description of the database in different paper is base on the response of the API, but this is not the real structure of the database, so, for this reason, I was searching for this more detailed description.

For this I've found e.g. "An Introduction to OpenStreetMap" by Mele Sax-Barnett 2014 . This is a little outdated but seems to be a rather road online overview. In order to be up-to-date replace following links there: * ignore e.g. http://market.weogeo.com/ - and replace with https://osmaxx.hsr.ch/ * Replace TileMill - with https://maputnik.github.io/ * Replace slide "The Future: Vector tiles" - e.g. with https://openmaptiles.org/ That's all incomplete and just scratching the surface. So pls. read up first what OSM is and - before all - edit something in OSM (e.g. building addresses or shops you know) in order to understand how OSM works. :Stefan  http://pdxmele.com/intro-osm/OSM_intro_workshop.pdf Am Fr., 3.

I found at this page  an image that describes the schema of the database, but elements in the table are not described. Instead, I found in this page  a description of the Node element, but there are not all the elements present in the image . Exist a page that describes all the database schema?
