Top Open source NoSQL database programs

NoSql, it stands for Not Only SQL, refers to the non-relational database. The next generation database mainly addresses several key points: non-relational, distributed, open source, and horizontally scalable.  The non-relational database has developed very rapidly due to its own characteristics. The NoSQL database was created to solve the challenges brought by the multiple data types of large-scale data collection, especially the big data application problem. It also supports easy replication, simple APIs, final consistency (non-ACID), and large data. It is stored by us with the most key-values, and of course other document types, column stores, graph databases, XML databases, and so on. Here are some top available NoSQL database programs in Open source or free category.

Note: This article only listing the NoSQL database programs available online, we haven’t reviewed, so we can’t say which NoSQL database is best to what scenario.

 

Oracle NoSQL Database

Oracle NoSQL Database is an open source non-SQL distributed the key-value database. Developed by Oracle  Corporation.  In short, it is known as OND that uses the Oracle Berkeley DB Java Edition high-availability storage engine.

MongoDB

MongoDB is a database based on distributed file storage. By the C ++ written language. Designed to provide scalable, high-performance data storage solutions for web applications.

mongoDB nosql database program

MongoDB is a product between a relational database and a non-relational database. It is the most versatile and most relational database in a non-relational database. It supports input of data is very taken flexible manner, the scheme is very much similar to JSON  format so it can store more complex data types. The biggest feature of Mongo is that it supports a very powerful query language. Its syntax is similar to the object-oriented query language. It can perform almost all the functions of relational database single-table query, and also supports indexing data. MongoDB is available in three versions Community (free), Enterprise (subscription based) and Atlas available as an on-demand fully managed service. Its core features are Ad hoc queries, Indexing, Replication, Load balancing, File storage, Aggregation, Server-side JavaScript execution, Capped collections and Transactions.

Apache Cassandra

Cassandra is a hybrid, a NoSQL database program similar to Google’s BigTable. The main feature of Cassandra is that it is not a database, but a distributed network service composed of a bunch of database nodes. A write operation to Cassandra will be copied to other nodes, and the read operation of Cassandra will also be Route to a node to read. For a Cassandra cluster, scaling performance is a relatively simple matter, just add nodes to the cluster.

Cassandra’s main features are richer than Dynamo (distributed Key-Value storage system), but the support is not as good as document storage MongoDB (an open source product between relational and non-relational databases, the most versatile of non-relational databases).


 

Cassandra was originally developed by Facebook and later turned into an open source project. It is an ideal database for social networking cloud computing. It features- No single point of failure as data is distributed across the cluster; Supports replication and multi-data centre replication; Horizontal scalability, Fault-tolerant, Tunable consistency, MapReduce support, Cassandra Query Language (CQL); management and monitoring via Java Management Extensions (JMX) and more…

Redis

Redis NoSQL database

Redis acronym that stands for Remote Dictionary Server which one of the most popular NoSQL database programs. It is an in-memory key-value database with a built-in net interface written in ANSI-C for Posix systems. There are also some opinions that Redis is a memory database because its high performance is based on the basis of memory operations. Others think that Redis is a data structure server because Redis supports complex data features such as List, Set, HyperLogLogs, bitmaps, streams, spatial indexes and so on. However, the role of Redis determined by how you use it. Redis is an open source NoSQL database and free to use.

Apache CouchDB

CouchDB is an open source, document-oriented NoSQL database program accessible through the RESTful JavaScript Object Notation (JSON) API. The term “Couch” is an acronym for “Cluster Of Unreliable Commodity Hardware”, which reflects CouchDB’s goal of being highly scalable, providing high availability and high reliability, even on hardware that is prone to failure. CouchDB was originally written in C++, but in April 2008, the project moved to the Erlang OTP (programming language-wiki) for concurrency, distribution and fault tolerance.

Apache CouchDB NoSQL database programe

Its data storage method is somewhat similar to Lucene ‘s index file format. The biggest significance of CouchDB is that it is a new generation storage system for web applications. CouchDB implements a form of multi-version concurrency control (MVCC) so it does not lock the database file during writes. Conflicts are left to the application to resolve. CouchDB is built on top of a powerful B-tree storage engine; it is responsible for sorting the data in CouchDB and provides a mechanism for performing a search, insert, and delete operations within the log-sharing time. CouchDB uses this engine for all internal data, documents, and views.

The Map/Reduce feature in CouchDB generates key/value pairs, and CouchDB inserts them into the B-tree engine and sorts them according to their keys. This enables efficient lookups with keys and improves the performance of operations in the B-tree. In addition, this means that data can be partitioned across multiple nodes without having to query each node individually.
