What is NoSQL and its types?

There are four big NoSQL types: key-value store, document store, column-oriented database, and graph database. Each type solves a problem that can’t be solved with relational databases. Actual implementations are often combinations of these. OrientDB, for example, is a multi-model database, combining NoSQL types.

Is Cassandra a NoSQL database?

Apache Cassandra™ is a distributed NoSQL database that delivers continuous availability, high performance, and linear scalability that successful applications require.

Why is it called NoSQL?

The acronym NoSQL was first used in 1998 by Carlo Strozzi while naming his lightweight, open-source “relational” database that did not use SQL. The name came up again in 2009 when Eric Evans and Johan Oskarsson used it to describe non-relational databases.

How does NoSQL work?

NoSQL is an approach to databases that represents a shift away from traditional relational database management systems (RDBMS). … Relational databases rely on tables, columns, rows, or schemas to organize and retrieve data. In contrast, NoSQL databases do not rely on these structures and use more flexible data models.

What is NoSQL data model?

NoSQL databases (aka “not only SQL”) are non tabular, and store data differently than relational tables. NoSQL databases come in a variety of types based on their data model. The main types are document, key-value, wide-column, and graph.

MongoDB, CouchDB, CouchBase, Cassandra, HBase, Redis, Riak, Neo4J are the popular NoSQL databases. MongoDB, CouchDB, CouchBase are document-oriented NoSQL databases, Redis and Riak are key-value stores, Cassandra and HBase are column family stores and Neo4J is a graph database.

What is the aim of NoSQL?

NoSQL systems are purpose-built solutions, designed to address specific technical requirements. NoSQL systems originated to provide high throughput, fault-tolerant horizontally scalable simple data storage and retrieval with a bare minimum of additional functionality.

What are the disadvantages of NoSQL?
