The SQL databases uses Structured Query Language whereas NOSQL databases use Unstructured Query Language which varies from database to database. 1.2 Features of NoSQL Databases: Schema on Read: There is no definite schema on the underlying data in the databases and it leads to high flexibility on the storage Nonrelational: In traditional databases there are relations between the tables. For example, a list of transaction details can be connected to a separate list of delivery details. With a NoSQL database, this information is stored as an aggregate — a single record with everything about the transaction, including the delivery address Commodity hardware: With a NoSQL database, cheap commodity hardware can be used. Adding more of these cheap servers allows NoSQL databases to scale to handle more data. Highly distributable: With a NoSQL database, a cluster of servers can be used to hold a single large database 2. Different Types of NOSQL databases There are many types of non-relational databases but more often than not, they fall under one of the following categories: 2.1 Document Model In a document model, data is stored in documents.
