Question 23

Which of the following is true about a document store:
document stores cannot promise atomicity
A document store naturally maintains relationships between nearest neighbors and
connections among entities.
A document store is an extension of a key-value database, in which the value is now a
complex semi-structured object, like json
document stores do not typically rely on partitioning and sharding

Answer 1

A document store is indeed an extension of a key-value database with values like JSON, which allows for more complex semi-structured data handling.

Therefore, the correct answer is: option 'A document store is an extension of a key-value database, in which the value is now a complex semi-structured object, like json'.

Step-by-step explanation:

A document store is a type of NoSQL database that is designed to store and manage semi-structured data, such as JSON or XML. It is an extension of a key-value database, where the value is now a complex semi-structured object, like JSON.

Among the given options, the statement that is true about a document store is that it is an extension of a key-value database, in which the value is now a complex semi-structured object, like JSON.

This allows for storing and retrieving more complex data than simple key-value pairs, thereby adding flexibility to the types of data that can be handled efficiently. Document stores typically support atomicity at the document level and also make use of partitioning and sharding to manage and scale large datasets.
