Web Apps Rely on Web Principles

If you work for a traditional software company that wants to sell a Web application, be aware that installable software does not quickly convert into a Web application. Nor can it always be converted into a successful Web application. Your company must adopt Web principles for design, development, testing, security, IT, marketing, sales, billing, documentation, support, and training.

From an application design perspective, a Web application requires a relatively simple interface. Standard HTML provides the best cross-platform, cross-browser compatibility (see Figure A10.2). But if you use standard HTML, each page may be limited to only a few atomic actions, and you cannot offer direct manipulation of objects in a page, except for buttons and input fields (see Figure A10.3). If you use Dynamic HTML, you can add direct manipulation and create applications that look and feel very similar to installable desktop software. But only when a single standard implementation of Dynamic HTML exists will the extra work to make pages work across browsers be eliminated.
