1
Top 5 Most Acceptable Open Source Databases
Of the World
2
Introduction

• The volumes of data are ever increasing. With a
  lot of data generated each minute on social media
  and networking sites and through extensive
  analyses and studies, the internet is overloaded.
  
• This rising volume of data has presented a novel
  challenge to us- that of its management, storage,
  and handling.
• Open-source databases have evolved to be
  sought-after database management systems today,
  with strong features in place that result in
  efficient data management and quick retrieval
  capabilities.

• Today, we see an overview of the best Open-source
  database management software that are currently
  leading with their popularity and widespread
  appeal.

MongoDB

• MongoDB is the most popular open-source database
  management system.
• The software platform arrived in the mid-2000s
  under the class of NoSQL database management
  systems.
• The open-source software did away with the method
  of storing data in rows and columns in a database
  system and stored data in JSON like structures
  that had dynamics schema, and termed the
  structure BSON later.
• MongoDB is written in C and boasts of scores of
  features like- storing records in the form of
  documents and storing data corresponding to data
  types used in most programming languages, support
  for polymorphism through a dynamic schema,
  complete index support on all fields, etc.

4
MySQL

• While MongoDB is the most trending choice, MySQL
  is the one that has been around for the longest-
  about 30 years, and has evolved a lot since its
  inception.
• Scores of GUI and command-line tools are used now
  to access and manage MySQL through command-line
  or GUI tools.
• MySQL is a popular choice for the PHP programming
  languages developers who work to build web
  applications using Relational Database Management
  Systems.
• The database management software is available in
  two different editions- the open source MySQL
  community edition and an enterprise edition.
• The enterprise edition gets better support and
  more frequent updates.

5
PostgreSQL

• PostgreSQL powers magnificent organizations like
  Fujitsu, Cisco, and ADP.
• The database management software which is nor
  popular nor widespread has a liberal open-source
  license, that permits the users of the software
  to freely modify the code to fit their company's
  specific needs and requirements.
• PostgreSQL is an object-oriented RDBMS that
  promotes extensible and standard compliance.

• Some of the features of the platform include
  support for SQL data types, multi-version
  concurrency control, transaction reliability
  through ACID concept, etc.

6
Cassandra

• This database management system was
  initially java web development company by the
  engineers at Facebook to power the search
  functionality of the social media giant.
• Later, the software was made open-source.
• Cassandra is a distributed database management
  system that handles the data that is spread
  across a large number of devices in a cluster
  formation.
• Cassandra considers scalability and performance
  to be of high importance.
• Cassandra powers the leading web infrastructure
  companies like Twitter, Apple, and Netflix.

• Some of the standout features of the platform
  include decentralization of data, replication of
  multiple data centres, and a Cassandra Query
  Language (CQL), an alternative to SQL that
  resembles the latter.

7
CounchDB

• Like MongoDB, CouchDB also uses the same file
  notation format in its database management
  features- the JSON format. Some large
  corporations that rely on the database system
  are- BBC, Canonical, and Sophos.
• Some of its unique features include- offline
  editing, distributed architecture for data
  replication and security, ACID semantics
  compliance, etc.
