Hypertext Markup Language (HTML) used to interpret and compose text, images, and other material into visual or audible web pages displayed in a web browser. HTML is enhanced by technologies like Cascading Style Sheets (CSS) and scripting languages like JavaScript.
Asynchronous JavaScript and XML (AJAX) A set of web development techniques using many web technologies on the client-side to create asynchronous web applications. AJAX allows web pages and, by extension, web applications, to change content dynamically without the need to reload the entire page.
Cascading Style Sheets (CSS) describes how HTML elements are displayed on a device screen, including content, layout, colors and fonts. CSS enables multiple web pages to share formatting by specifying a separate .css file which reduces complexity and repetition in the structural content.
PHP a general-purpose scripting language especially suited to web development. PHP first stood for Personal Home Page, but it was later changed to PHP Hypertext Preprocessor using its old acronym in the new name.
Practical Extraction and Report Language (PERL) A family of two high-level, general-purpose, interpreted, dynamic programming languages using a syntax similar to C or C++. Perl includes powerful tools for processing text that make it ideal for working with HTML, XML and all other mark-up languages commonly used by Web programmers to create scripts for Web servers.
JavaScript an object-oriented scripting language used primarily by Web browsers to create a dynamic and interactive experience for the user. Alongside HTML and CSS, JavaScript is one of the core technologies of the World Wide Web.
Python an interpreted, high-level and general-purpose programming language. Its language constructs an object-oriented approach aimed to help programmers write clear, logical code for projects.
XSL Transformations (XSLT) used to transform an XML document into another XML document, or another type of document that is recognized by a browser, like HTML and XHTML. XSLT does this by transforming each XML element into an (X)HTML element.
Structured Query Language (SQL) used in programming for managing data held in a Relational DataBase Management System (RDBMS). SQL includes data query, data manipulation insert, update and delete, and data access control.
