In a word: Flex. Adobe Flex makes beautiful GUIs and it is a wonderful technology to use for development. Your end users and also your developers will love you for choosing Flex. If your marketing department gets involved and says you have to deliver a pure HTML solution then you won't be able to use Flex. Probably you will want to use some development platform that delivers Dynamic HTML and Ajax. There are lots to choose from. Yes ColdFusion is very old and shouldn't be used for new projects at this point. - Mitch Gart -----Original Message----- From: ACM SIGCHI WWW Human Factors (Open Discussion) [mailto:[log in to unmask]] On Behalf Of Deb Brown Sent: Thursday, November 29, 2007 11:09 PM To: [log in to unmask] Subject: [CHI-WEB] Current thinking on Best GUI development platforms Hi all- Question regarding GUI dev platforms - what is the current thinking as to best in class platforms for presentation layer development ? I have a client who has recently suggested that they might build their UI on ColdFusion. My understanding is that is a very old platform, am I correct? Thanks for your input. -deb -------------------------------------------------------------- Tip of the Day: Postings must be in plain text CHI-WEB: www.sigchi.org/web POSTINGS: mailto:[log in to unmask] MODERATORS: mailto:[log in to unmask] SUBSCRIPTION CHANGES & FAQ: www.sigchi.org/web/faq.html -------------------------------------------------------------- -------------------------------------------------------------- Tip of the Day: Quote only what you need from earlier postings CHI-WEB: www.sigchi.org/web POSTINGS: mailto:[log in to unmask] MODERATORS: mailto:[log in to unmask] SUBSCRIPTION CHANGES & FAQ: www.sigchi.org/web/faq.html --------------------------------------------------------------
