Detailed explanation-1: -Unstructured data can be stored in a number of ways: in applications, NoSQL (non-relational) databases, data lakes, and data warehouses. Platforms like MongoDB Atlas are especially well-suited for housing, managing, and using unstructured data.
Detailed explanation-2: -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-3: -Which of the following statements is true of NoSQL databases? They don’t support any Structured Query Language (SQL) functions. They are useful for managing large sets of distributed data.
Detailed explanation-4: -NoSQL databases store data in documents rather than relational tables. Accordingly, we classify them as “not only SQL” and subdivide them by a variety of flexible data models. Types of NoSQL databases include pure document databases, key-value stores, wide-column databases, and graph databases.
