Due to this … The most common types of NoSQL databases are key-value, document, column and graph databases. A NoSQL database includes simplicity of design, simpler horizontal scaling to clusters of machines and finer control over availability. Infrastructure. Infrastructural technologies are the core of the Big Data ecosystem. In some of the other videos, we discussed Big Data technologies such as NoSQL databases and Data Lakes. Introduction NoSQL, for ―Not Only SQL,‖ refers to an eclectic and increasingly familiar group of non-relational data management systems; where databases are not built primarily on tables, and generally do not use SQL for data manipulation [1]. NoSQL promised to upend the database market as big data forced a sea change in how we think about and manage data. Movement from data warehouses and data lakes to databases. While NoSQL databases have existed for many years, NoSQL databases have only recently become more popular in the era of cloud, big data and high-volume web and mobile applications. These documents hold a lot of different key-value pairs, as well as key-array pairs or sometimes nested documents. NoSQL databases can store data in graphs and documents.
