PLEASE answer all questions correctly based on PYTHON.
THANK YOU SO MUCH, please answer them all
Question 14 (1 point)
Which of the following statements is false?
Question 14 options:
For decades, relational database management systems (RDBMs) have
been the standard in data processing.
RDBMs require unstructured data that fits into neat rectangular
tables.
As the size of the data and the number of tables and
relationships increases, relational databases become more difficult
to manipulate efficiently.
In today's big-data world, NoSQL and NewSQL databases have
emerged to deal with the kinds of data storage and processing
demands that traditional relational databases cannot
meet.
Question 15 (1 point)
Which of the following statements a), b) or c) is false?
Question 15 options:
NoSQL means what its name implies.
NoSQL databases are meant for unstructured data, like photos,
videos and the natural language found in e-mails, text messages and
social-media posts, and semi-structured data like JSON and XML
documents.
Semi-structured data often wraps unstructured data with
additional information called metadata.
All of the above statements are true.
Question 16 (1 point)
Which of the following statements a), b) or c) is false?
Question 16 options:
The four NoSQL database categories are hierarchical, document,
columnar (also called column-based) and graph.
NewSQL databases blend features of relational and NoSQL
databases.
We presented a case study in which we stored and manipulated a
large number of JSON tweet objects in a NoSQL document database,
then summarized the data in an interactive visualization displayed
on a Folium map of the United States.
All of the above statements are true.
Question 17 (1 point)
Which of the following statements a), b) or c) is false?
Question 17 options:
A document database stores semi-structured data, such as JSON or
XML documents.
In document databases, you typically add indexes for specific
attributes, so you can more efficiently locate and manipulate
documents.
The most popular document database (and most popular overall
NoSQL database) is Neo4j.
All of the above statements are true.
Question 18 (1 point)
Which of the following statements a), b) or c) about graph
databases is false?
Question 18 options:
A graph database models relationships between objects.
The objects are called nodes (or vertices) and the relationships
are called edges.
Edges are bidirectional.
All of the above statements are true.
Question 19 (1 point)
Key advantages of relational databases include their security
and transaction support. In particular, relational databases
typically use ACID—Atomicity, Consistency, Isolation, Durability
transactions. Which of the following ACID attributes is described
by: "ensures that concurrent transactions occur as if they were
performed sequentially?"
Question 19 options:
Consistency
Isolation
Durability
Question 20 (1 point)
Which of the following statements a), b) or c) is false.
Question 20 options:
The types of applications that use NoSQL databases typically do
not require the guarantees that ACID-compliant databases
provide.
Many NoSQL databases typically adhere to the BASE (Basic
Availability, Soft-state, Eventual consistency) model, which
focuses more on the database's availability.
Whereas, BASE databases guarantee consistency when you write to
the database, ACID databases provide consistency at some later
point in time.
All of the above statements are true.
