This type ensures that data stays together when used in applications. These values come in various types, such as arrays, Booleans, numbers, objects, and strings. Document-oriented: This model stores data as documents, usually in JSON, XML, or BSON (binary JSON) formats, with each document containing pairs of fields and values.You often see this kind of database used in web applications that need to store and cache user-session data, such as for gaming or shopping apps. Key-value: Considered the simplest type, this is a schema-less data model that houses data in a dictionary of key-value pairs, meaning each item has a key and a value.This means that, if some piece of the database is taken offline, the rest of the database remains functional and accessible.Д«roadly speaking, there are four major types of NoSQL databases: NoSQL databases are also considered distributed, meaning that data is stored on multiple local or remote servers. NoSQL databases have not rendered relational databases obsolete but simply provided a viable alternative for relevant use cases. Without the need to connect tables, developers could use NoSQL databases to divide search-query and data-storage workloads across multiple database servers, instead of relying on a single server. In the era of Big Data, however, increasing demand for faster and more disparate use of large data sets led to the development of NoSQL or non-relational databases.

This interface allowed them to organize data into tables that were then linked based on shared data. NoSQL stands for вЂњnon-SQLвЂќ or вЂњnot only SQL.вЂќ Structured Query Language (SQL) is a programming language developed in the early 1970s to allow programmers to interface with relational database management systems (RDBMS).
