Hi All.
While CakePHP provides an EXCELLENT framework for coding PHP apps.
When it comes to tools which help aid in the design phase of
application development, some of you might have adopted some
techniques to streamline the analysis and design phase.

For creating databases and CakePHP models, i would opt for DBDesigner
combined with dbdesigner2cake.
DBDesigner allows easy creation of ERDs as well as implementation of
databases in various DBMSs. dbdesigner2cake (http://
dbdesigner2cake.cirello.org/) as per its site "DBDesigner 4 Scaffold
Tools for CakePHP".

But what about modeling business logic and user interfaces.
My approach would be to model business logic in DFDs (would be great
to see a DFD to PHP app), while prototyping user interfaces in image
manipulation tools such as Photoshop.

What form of documentation, processes and tools are folks using for
application design?
