👐 Clean book attributes up

We want to clean up the book_attributes array in our MongoDB schema. We want an array of objects containing attributes, modelled a key value pairs. something like:

{
    "_id": 838383, // book id
    "attributes": [
        {
            "key": "price",
            "value": 11
        },
        {
            "key": "pages",
            "value": 236
        },
        // ...
    ] 
}

• On the MongoDB diagram view, click the books collection
• On the relational mappings list on the right, click on the edit icon of book_attribute embedded array mapping rule.
• Change the Field name from bookAttributes to attributes
• Uncheck bookId. We just want all the attributes, which are key/value pairs.
• Click Save and close

Here we've implemented the Attribute Pattern for MongoDB. This will allow for easy indexing, querying based on attributes and extension of attributes.
