The way we read the article 13 is that platforms have to offer tools to identify copyrighted work, but also the rights holders have to register the work for them to be identified.
That would imply that one database with an obvious way for rights holders to register their content should be the right way to go.
But we will not know up until an EU country actually writes the law.

Having a single database seems unusually problematic. If there is only one operator, who is that supposed to be? What happens if/when they give up or go out of business? What happens when they charge monopoly rents or their system is unreliable or full of bugs?
On the other hand, if there is one submission process that submits works to everybody's database and people have their own copies, that seems like it would be of particular interest to pirates -- go sign up as a database recipient and the copyright holders will send you copies of all their works.
It's as if no one has even attempted to think through how this would work.
