ColdFusion
ColdFusion is a commercial rapid web application development platform created by Adobe (formerly Macromedia and Allaire). It uses its own scripting language, CFML (ColdFusion Markup Language), to build dynamic web applications, integrate with databases, and generate HTML, XML, or other content. The platform includes a web server, application server, and development tools, often used for enterprise-level applications due to its built-in features for data handling, security, and scalability.
Developers should learn ColdFusion when working on legacy enterprise systems, government projects, or specific industries (like finance or healthcare) where it's still in use, as it allows rapid prototyping and simplifies complex tasks like database integration and PDF generation. It's particularly valuable for maintaining or modernizing existing ColdFusion applications, where knowledge of CFML and Adobe's ecosystem is essential for updates, migrations, or integration with newer technologies.
