What is available in the realm of software that makes a pretty user interface for a web-based database application?
Both free and paid software (up to about $1,200) will be considered. The database application will be hosted on a typical Linux-based server that uses PHP5 and XHTML/CSS for the website. The actual data will be kept in either MySql or Postgress.
Ease of development (i.e., development of the user interface and the way it is programmed to interact with the data in the database) is the most important factor. In this specific case, calls to the server for screen updates is acceptable (AJAX is not required, but will be considered if it is the easiest to develop). Again, ease of development is the paramount factor in the software being sought.
I'd suspect that many of the users here do not use such software, as it seems most build their web apps from scratch, or using development tools but still do the coding.
I have not used either Alpha5 nor RealStudio, but some lesser versions of that software could be Dreamweaver or Frontpage, both of which I have used and work well for what they are intended to do. If you are looking to work on a serious project, I wouldn't suspect to be able to do the whole thing without any technical expertise. Perhaps for that $1200 (if the project is small enough) you can hire a developer to do some of the work for you.
