PostgreSQL, often simply Postgres, is an object-relational database (ORDBMS) i.e. an RDBMS, with additional (optional use) "object" features with an emphasis on extensibility and standards compliance.

As a database server, its primary functions are to store data securely and return that data in response to requests from other software applications.

It can handle workloads ranging from small single-machine applications to large Internet-facing applications (or for data warehousing) with many concurrent users; on macOS Server, PostgreSQL is the default database; and it is also available for Microsoft Windows and Linux (supplied in most distributions).

MySQL (officially pronounced as "My S-Q-L") is an open-source relational database management system (RDBMS).

Its name is a combination of "My", the name of co-founder Michael Widenius' daughter, and "SQL", the abbreviation for Structured Query Language.

The MySQL development project has made its source code available under the terms of the GNU General Public License, as well as under a variety of proprietary agreements.

MySQL was owned and sponsored by a single for-profit firm, the Swedish company MySQL AB, now owned by Oracle Corporation.

For proprietary use, several paid editions are available, and offer additional functionality.

MariaDB is a community-developed fork of the MySQL relational database management system intended to remain free under the GNU GPL.

Development is led by some of the original developers of MySQL, who forked it due to concerns over its acquisition by Oracle Corporation.

Contributors are required to share their copyright with the MariaDB Foundation.

HeidiSQL, previously known as MySQL-Front, is a free and open source client, or frontend for MySQL (and for its forks like MariaDB and Percona Server), as well as Microsoft SQL Server and PostgreSQL.

To manage databases with HeidiSQL, users must log in to a local or remote MySQL server with acceptable credentials, creating a session.

Within this session users may manage MySQL databases within the connected MySQL server, disconnecting from the server when done.

Its feature set is sufficient for most common and advanced database, table and data record operations, but it remains in active development to move towards the full functionality expected in a SQL database frontend.

The open-source model is a decentralized development model that encourages open collaboration.

A main principle of open-source software development is peer production, with products such as source code, blueprints, and documentation freely available to the public.

The open-source movement in software began as a response to the limitations of proprietary code.

The model is used for projects such as in open-source appropriate technologies, and open-source drug discovery.
