No, horrible job at explaining. What does it mean to turn any set of notes into a powerful database? What does it mean to "turn"? Does it mean that a file will become a database? Or does it mean that a file can be interpreted as a database? And why set of notes? If I have a single note, can I turn that into a database too? Are the records of the database files, or items in a file? What is happening when I type ![[Untitled.base]]? Is the file where I typed that a database now? Or does that text assume that the file named Untitled must be a database?
They do a horrible job at explaining it.
