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).

Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation of a document written in a markup language.

Although most often used to set the visual style of web pages and user interfaces written in HTML and XHTML, the language can be applied to any XML document, including plain XML, SVG and XUL, and is applicable to rendering in speech, or on other media.

Along with HTML and JavaScript, CSS is a cornerstone technology used by most websites to create visually engaging webpages, user interfaces for web applications, and user interfaces for many mobile applications.

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.

MongoDB (from humongous) is a free and open-source cross-platform document-oriented database program.

Classified as a NoSQL database program, MongoDB uses JSON-like documents with schemas.

MongoDB is developed by MongoDB Inc. and is free and open-source, published under a combination of the GNU Affero General Public License and the Apache License.

In computing, JSON (canonically pronounced; sometimes JavaScript Object Notation) is an open-standard format that uses human-readable text to transmit data objects consisting of attribute–value pairs.

It is the most common data format used for asynchronous browser/server communication, largely replacing XML, and is used by AJAX.
