Here is how I understand it, maybe the OP will find it useful.
Think of SQL server as a shopping mall, the databases are individual shops, and the main car park is windows.
To get into the car park (windows) I need a car park pass.
To get into the shopping mall (SQL Server) I will also need another pass.
Finally, to get into a shop (database), I need a third pass.
Of course in real life a shopping centres don't quite work like this but you get the idea... Lol

It takes a minimal capacity for rational thought to see that the corporate 'free press' is a structurally irrational and biased, and extremely violent, system of elite propaganda.

Society has varying and conflicting interests; what is called objectivity is the disguise of one of these interests - that of neutrality. But neutrality is a fiction in an unneutral world. There are victims, there are executioners, and there are bystanders... and the 'objectivity' of the bystander calls for inaction while other heads fall.
