List of Top NoSQL Databases-[knowledge factory]

NoSQL, which stands for “not only SQL,” is an approach to database design that can accommodate a wide variety of data models, including key-value, document, columnar, and graph formats.NoSQL is an alternative to traditional relational databases in which data is placed in tables and data schema is meticulously designed before the database is built. NoSQL databases are especially utilizable for working with large sets of distributed data. 



NoSQL Features & Capabilities 

  • Performance 
  • Availability 
  • Multi-Model 
  • Concurrency 
  • Security 
  • Scalability 
  • Data Model Flexibility 
  • Deployment Model Flexibility 
Today, we will see a  list of top NoSQL databases.

MongoDB

MongoDB is a cross-platform document-oriented database program. Classified as a NoSQL database program, MongoDB uses JSON-like documents with optional schemas. Documents consist of key-value pairs which are the basic unit of data in MongoDB. Collections contain sets of documents and functions which is the equivalent of relational database tables. MongoDB is a database that came into the world around the mid-2000s.MongoDB is developed by MongoDB Inc. and licensed under the Server Side Public License.
Over the years, MongoDB has become a popular choice of a highly scalable database and it is currently being used as the backend data store of many well-known organizations like IBM, Twitter, Zendesk, Forbes, Facebook, Google, and a gazillion others.


Apache Cassandra

Apache Cassandra is a highly scalable, high-performance distributed database designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. It is a type of NoSQL database.
Cassandra is in use at Activision, Apple, BazaarVoice, Best Buy, CERN, Constant Contact, Comcast, eBay, Fidelity, Github, Hulu, ING, Instagram, Intuit, Macy's™, Macquarie Bank, Microsoft, McDonald's, Netflix, New York Times, Outbrain, Pearson Education, Sky, Spotify, Uber, Walmart, and thousands of other companies


Couchbase Server

Built on the most puissant NoSQL technology, Couchbase Server distributes unparalleled performance at scale, in any cloud. With features like memory-first architecture, geo-distributed deployments, and workload isolation, Couchbase Server excels at fortifying mission-critical applications at scale while maintaining submillisecond latencies and 99.999% availability. Plus, with the most comprehensive SQL-compatible query language (N1QL), migrating from RDBMS to Couchbase Server is facile with ANSI joins.


RavenDB

RavenDB is an open-source document-oriented NoSQL designed especially for the. NET/Windows platform. It requires commercial licensing  A free edition is available for open source projects, but it must be applied for. RavenDB supports multiple databases and, like other database servers, a database acts as a container of data. RavenDB can easily handle hundreds or thousands of databases on the same instance and was explicitly designed with multi-instances in mind. This allows RavenDB to manage large numbers of databases, but at any given time, only one database is active and taking resources.


Amazon DynamoDB

Amazon DynamoDB is a key-value and document database that delivers single-digit millisecond performance at any scale. It's a fully managed, multi-region, multi-active, durable database with built-in security, backup and restores, and in-memory caching for internet-scale applications. DynamoDB can handle more than 10 trillion requests per day and can support peaks of more than 20 million requests per second. 
Many of the world's fastest-growing businesses such as Lyft, Airbnb, and Redfin as well as enterprises such as Samsung, Toyota, and Capital One depend on the scale and performance of DynamoDB to support their mission-critical workloads. 


Apache HBase

HBase is an open-source non-relational distributed database modeled after Google's Bigtable and written in Java. It is developed as part of Apache Software Foundation's Apache Hadoop project and runs on top of HDFS or Alluxio, providing Bigtable-like capabilities for Hadoop.


Azure Cosmos DB

Azure Cosmos DB is a fully managed NoSQL database service for modern app development. Get guaranteed single-digit millisecond response times and 99.999-percent availability, backed by SLAs, automatic and instant scalability, and open-source APIs for MongoDB and Cassandra. Enjoy fast writes and reads anywhere in the world with turnkey multi-master global distribution.


Google Cloud Datastore

Datastore is a highly-scalable NoSQL database for your applications. Datastore automatically handles sharding and replication, providing you with a highly available and durable database that scales automatically to handle your applications' load. Datastore provides a myriad of capabilities such as ACID transactions, SQL-like queries, indexes, and much more.


Redis

Redis is an open-source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps,  geospatial indexes, and streams. Redis has built-in replication, Lua scripting, LRU eviction, transactions, and different levels of on-disk persistence, and provides high availability via Redis Sentinel and automatic partitioning with Redis Cluster.


Oracle NoSQL Database

Oracle NoSQL Database is a NoSQL-type distributed key-value database from Oracle Corporation. It provides transactional semantics for data manipulation, horizontal scalability, and simple administration and monitoring. Oracle released Oracle Autonomous NoSQL Database Cloud on August 10, 2018.


Neo4j

Neo4j is a native graph database, built from the ground up to leverage not only data but also data relationships. Neo4j connects data as it’s stored, enabling queries never before imagined, at speeds never thought possible.

With Neo4j, each data record, or node, stores direct pointers to all the nodes it’s connected to. Because Neo4j is designed around this simple, yet powerful optimization, it performs queries with complex connections orders of magnitude faster, and with more depth, than other databases.


AllegroGraph

AllegroGraph is a Horizontally Distributed, Multi-model (Document and Graph), Entity-Event Knowledge Graph technology that enables businesses to extract sophisticated decision insights and predictive analytics from their highly complex, distributed data that can’t be answered with conventional databases.

Unlike traditional relational databases or simple property graph databases, Franz’s product AllegroGraph employs a combination of document (JSON and JSON-LD) and graph technologies that process data with contextual and conceptual intelligence. Knowledge Graphs built on the AllegroGraph platform are able to run queries of unprecedented complexity to support predictive analytics that helps companies make better, real-time decisions.


Hypertable

Hypertable is a high performance, open-source, massively scalable database modeled after Bigtable, Google's proprietary, massively scalable database.
