Can NoSQL database store structured data?

What kind of data can be stored in NoSQL databases?

Types of NoSQL databases Document databases store data in documents similar to JSON (JavaScript Object Notation) objects. Each document contains pairs of fields and values. The values can typically be a variety of types including things like strings, numbers, booleans, arrays, or objects.

Does NoSQL come under unstructured data?

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.

Can structured data be stored in a database?

As for databases, structured data is usually stored in a relational database (RDBMS), while the best fit for unstructured data instead is so-called non-relational, or NoSQL databases.

Can we store unstructured data in MongoDB?

MongoDB's document data model is particularly well suited for storing unstructured data. It stores all related data together within a single document, and doesn't require data to fit neatly into the rigid structure of relational rows and columns. Unstructured data can represent both a challenge and an opportunity.

What is a NoSQL database?

NoSQL databases can store structured, semi-structured and unstructured data. Their main advantages focus on semi-structured (JSON, XML, not all fields are known) and unstructured.

Can BLOB data be stored in NoSQL database?

NoSQL databases can store structured, semi-structured and unstructured data. Their main advantages focus on semi-structured (JSON, XML, not all fields are known) and unstructured. But, you can safely store BLOB in a RDBMS, e. g., Oracle Database and many others relational databases.

Are NoSQL and unstructured data new or old?

NoSQL and Unstructured Data are not new anymore (at least not for the last 20 years). NoSQL has not displaced RDBMS. NoSQL complements SQL for some use-cases, but SQL can also already handle maybe 95% of data use-cases today including Unstructured Data.

What are the different types of NoSQL datastores?

NoSQL datastores cater to semi-structured data types: key-value, wide column, document (tree), and graph. A key-value store is a dictionary or hash table database. It is designed for CRUD operations with a unique key for each record:
