An application development tool from Adobe for writing Web pages that interact with databases. Instead of writing tedious CGI and Perl scripts, operations are coded in the ColdFusion Markup Language (CFML) which uses HTML-like tags embedded in the Web pages. The ColdFusion engine, which interfaces with a Windows-based Web server, interprets the codes, accesses the database and delivers the results as HTML pages for the Web browser. ColdFusion was originally developed by Allaire Corporation, Cambridge, MA, which merged with Macromedia in 2001. In 2005, Macromedia was acquired by Adobe.
