ColdFusion Markup Language, more commonly known as CFML, is a scripting language for web development that runs on the JVM, the .NET framework, and Google App Engine. Multiple commercial and open source implementations of CFML engines are available, including Adobe ColdFusion, Lucee, New Atlanta BlueDragon (who makes both a Java-based and a .NET-based version), Railo, and Open BlueDragon as well as other CFML server engines.
In its simplest form, like many other web scripting languages, CFML augments standard HTML files with database commands, conditional operators, high-level formatting functions, and other elements to produce web applications. CFML also includes numerous other constructs including ColdFusion Components (CFCs), CFML's version of objects, that allow for separation of business logic from presentation.
CFML can be written using either tags or CFScript, which resembles JavaScript (ECMA script).
The pages in a CFML application include the server-side CFML tags and functions in addition to HTML tags, and modern CFML applications also tend to have CFCs that are accessed by the CFML pages for executing business logic. When a web browser requests a page in a ColdFusion application, it is automatically pre-processed by the ColdFusion application server.
