Thoughts on a Database database and MasterDatabase Database

When in a list view the context filter is enabled, a new entity created through the New button in the view, automatically gets populated the fields that are present in the global filter settings in the view.
But that is not the case when the views context filter is disabled.

So in order to always be able to automatically populate fields through the New button in a view that lists entities not contextually related to the current entity, the only option is to relate to a parent database, but I see thats its more reliable and solid to create a master database ‘MDB’ with one single entity, that relates to all entities of the workspace.

I did a similar thing for the purpose of linking each entity with an entity of database ‘DB’, such that for example an entity of database Page is always related to the entity Page of database DB. This has major benefits in filtering by database in views.

Would there be a more elegant way to accomplish both cases?

I saw a short wile ago a mention of Global databases being in the planning in fibery, that could related to all entities, or am I misunderstanding that?
Also, will the future polymorphic relations be able to cover these cases somehow?

I don’t know what mentions you’re thinking of, but I reckon any talk of ‘global’ databases is with reference to databases which are not tied to a specific space.
I don’t think this is what you have in mind.

Polymorphism is often used to describe the situation where an entity could relate to other entities of several different types, via a single relation field. Again, I don’t think it is what you have in mind.

You’re correctly describing that any applied context filters affect the field values of newly created entities.
But I’m not sure what the true problem you’re trying to solve is.

It sounds like you are simply wanting to apply preset default field values irrespective of any view filters applied?
I’m don’t understand how this leads to a desire for a ‘master’ database to which every entity in the workspace is connected.
