Flash or Flex Application with MySQL database

Hi, I'm not sure if this would be Flash or Flex. And it is not really a game, it's more of a web application. Please see this prototype: <[login to view URL]> This? is a very basic idea of our client's intention to offer a financial planning tool that charts a client's investment timeline from "cradle to grave." Thus the "Road to Prosperity." The client wishes to have a series of dynamic, user-placeable icons to represent various stages of investment, i.e., Childbirth, College, Marriage, New Home, etc. Client will be able to choose from this list and place the appropriate icon anywhere along a chronological map, add custom text/images to note the entry and allow for Additional Investment Options as needed. In the simplest forms, the requirements are: • Editable text • Pop-up notes for graphic icons • Application connectivity - connects w/DB, pulls in data via XML • Chronology Icons - add/delete as needed, movable, editable • Interface design • DB setup/design Please let me know if you have some experience with amy similiar Flash or Flex projects. Thanks!
