I don't think academics associate Knuth with any definition of databases. I 
believe you are referring to Codd's definition of the relational model, and 
I would be surprised if Codd ever said that a database using a different 
model can not be called a database. Textbooks used to teach undergrads 
about databases generally discuss several different database models, not 
just the relational one. These days, they may contain a section on XML 
databases.

But by your definition, only a relational database is a database.

Most people here are not using your terminology.
