• BSON

• JSONB

• True

• False

What makes a good schema?(multiple correct)

• Operations touch as few documents as possible

• Cache is not wasted on unwanted records

• Existing data is rewritten for redundancy

• All of the given

For MongoDB, schema design should focus on the application and not the data

• True

• False

What is a payload field?

• Metadata we examine inside MongoDB

• Data we just store and retrieve but do not process

• Data used for querying

• Data used for indexing

Which of the following are Schema Design patterns?

• Bucketing pattern

• All of the given

An e-commerce product description where we might need to search with any new attribute field would be an example of

• Bucket patterns

• IoT pattern

• Versioning pattern

• Attribute pattern

Storing IoT data efficiently would be possible through

• Attribute pattern

• Bucket pattern

• Versioning pattern

• IoT pattern

Following are the schema anti-patterns for MongoDB(multiple correct)

• • Very large 1 dimensional arrays

• • Use of arrays

• Lots of fields at the same level / flat documents

• Nesting of documents

How does the Attribute pattern differ from the Bucketing pattern in Schema Design?

• Attribute pattern is used for versioning while Bucketing pattern is used for search optimization

• Attribute pattern is used for efficient storage while Bucketing pattern is used for managing relationships

• Attribute pattern is used for search optimization while Bucketing pattern is used for efficient storage

• Attribute pattern is used for managing relationships while Bucketing pattern is used for versioning
