NewSQL databases overview in DBMS Theory - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the sentence to describe NewSQL databases.

DBMS Theory

NewSQL databases combine the scalability of NoSQL with the [1] of traditional SQL databases.

Drag options to blanks, or click blank then click option'

Aconsistency

Bsimplicity

Cflexibility

Dspeed

Attempts:

3 left

💡 Hint

Common Mistakes

Choosing 'speed' because NoSQL is known for speed, but NewSQL focuses on consistency too.

Selecting 'flexibility' which is more related to NoSQL schema design.

NewSQL databases aim to provide the strong consistency guarantees of traditional SQL databases while scaling like NoSQL systems.

2fill in blank

medium

Complete the sentence about NewSQL architecture.

DBMS Theory

NewSQL databases often use a [1] architecture to handle many users and large data volumes efficiently.

Drag options to blanks, or click blank then click option'

Amonolithic

Bcentralized

Csingle-threaded

Ddistributed

Attempts:

3 left

💡 Hint

Common Mistakes

Choosing 'monolithic' which is a single large system, not scalable like NewSQL.

Selecting 'single-threaded' which limits performance.

NewSQL databases typically use a distributed architecture to scale horizontally and manage large workloads.

3fill in blank

hard

Fix the error in the statement about NewSQL features.

DBMS Theory

NewSQL databases support SQL queries and provide [1] transactions for reliable data operations.

AACID

Beventual consistency

CBASE

Dasynchronous

Attempts:

3 left

💡 Hint

Common Mistakes

Choosing 'eventual consistency' which is typical for NoSQL, not NewSQL.

Selecting 'BASE' which is a weaker consistency model.

NewSQL databases provide ACID transactions, ensuring Atomicity, Consistency, Isolation, and Durability.

4fill in blank

hard

Fill both blanks to complete the NewSQL database description.

DBMS Theory

NewSQL databases aim to provide [1] scalability and [2] consistency.

Drag options to blanks, or click blank then click option'

Ahorizontal

Beventual

Cstrong

Dvertical

Attempts:

3 left

💡 Hint

Common Mistakes

Choosing 'vertical' scalability which means upgrading a single machine.

Selecting 'eventual' consistency which is weaker than what NewSQL offers.

NewSQL databases provide horizontal scalability (adding more machines) and strong consistency (immediate data correctness).

5fill in blank

hard

Fill all three blanks to complete the NewSQL database characteristics.

DBMS Theory

NewSQL databases use [1] processing, support [2] queries, and ensure [3] durability.

Drag options to blanks, or click blank then click option'

Adistributed

BSQL

CACID

DNoSQL

Attempts:

3 left

💡 Hint

Common Mistakes

Choosing 'NoSQL' instead of 'SQL' for query support.

Selecting weaker consistency or durability models.

NewSQL databases use distributed processing, support SQL queries, and ensure ACID durability for reliable transactions.
