The equivalent document-based model has an individual document per beer; each document contains the same types of information for a specific beer.
The document-oriented approach provides several upsides compared to the traditional RDBMS model.
First, because information is stored in documents, updating a schema is a matter of updating the documents for that type of object. Secondly, we can distribute the information across multiple servers with greater ease.
You can also use one or more document to represent a real-world object.
The following compares a conventional table with document-based objects: In this example we have a table that represents beers and their respective attributes: id, beer name, brewer, bottles available and so forth.
The schema is the structure described in a formal language supported by the database and provides a blueprint for the tables in a database and the relationships between tables of data.
