NoSQL
C
Data Warehouse
D
None of the above
Explanation: 

Detailed explanation-1: -NoSQL databases are purpose built for specific data models and have flexible schemas for building modern applications. NoSQL databases are widely recognized for their ease of development, functionality, and performance at scale.

Detailed explanation-2: -NoSQL databases offer greater flexibility than SQL databases because they allow for the storage of different types of data in one place. This makes them ideal for applications that require more complex data structures.

Detailed explanation-3: -Flexibility: NoSQL databases are schema-less, meaning that they can handle unstructured and semi-structured data in addition to structured data. This flexibility makes it easier to store and manage a wide variety of data types, including documents, graphs, and key-value pairs.

Detailed explanation-4: -Does NoSQL have a schema? NoSQL databases do not have a schema in the same rigid way that relational databases have a schema. Each of the four main types of NoSQL database has an underlying structure that is used to store the data.

Detailed explanation-5: -While MongoDB is more flexible and ensures high and diverse data availability, a SQL Database operates with the ACID (Atomicity, Consistency, Isolation, and Durability) properties and ensures greater reliability of transactions.
