Couchbase Lite Datastructure Appoarch

I have many data models. How should I approach when I create my Couchbaselite database? Should create multiple database for every model. Then how should I join them?

Example Object Model:

Restaurant

Waiter

json String: [{ id=..., Name=Rest, adress={id=...,street=..}}]

You could use the same database for multiple models, and when you want to join, you could use alias(DataSource.database(db).as("main")) from same database(below example db) and join using it.

Below is a swift example, 

let q = QueryBuilder
        .select(SelectResult.expression(Meta.id.from("main")))
        .from(DataSource.database(db).as("main"))
        .join(
            Join.join(DataSource.database(db).as("secondary"))
                .on(Expression.property("prop1").from("main")
                    .equalTo(Expression.property("prop2").from("secondary"))))
