1. With SQL and HTML
2. Biometrics, though nametags help, if you can convince them to wear them
3. Following the XHTML specification

Not really helpful? That's okay. You didn't say what problem you were trying to solve.

The moral of the story: there is more than one way to do things because there is more than one thing to do. You either live with that ambiguity, or you spend the rest of your life trying to fit every problem to your ONE BEST solution.

Update: ... and that's why exploring other languages, paradigms (functional, imperative), and even design techniques (UML, design patterns, use cases) is important.
