Dynamic web page
Classical
hypertext navigation occurs among "static" documents, and, for web users, this experience is reproduced using
static web pages. However,
web navigation can also provide an interactive experience that is termed "dynamic". Content (text, images, form fields, etc.) on a
web page can change, in response to different contexts or conditions. There are two ways to create this kind of
interactivity: Using
client-side scripting to change interface behaviors within a specific
web page, in response to mouse or keyboard actions or at specified timing events. In this case the dynamic behavior occurs within the
presentation. Using
server-side scripting to change the supplied page source between pages, adjusting the sequence or reload of the
web pages or
web content supplied to the browser. Server responses may be determined by such conditions as data in a posted
HTML form, parameters in the
URL, the type of browser being used, the passage of time, or a database or server
state.

Pagina web dinamica
Una pagina web dinamica è una
pagina web il cui contenuto è, in tutto o in parte, generato sul momento dal
server e può essere quindi diversa ogni volta che viene richiamata. Questo significa che non si utilizza direttamente il linguaggio
HTML, ma che si ricorre a dei
linguaggi di programmazione (i linguaggi di scripting) che si occupano della creazione della pagina nel momento in cui questa viene visitata, anche interagendo con i visitatori, e possono variare l'
output HTML successivo dopo calcoli eseguiti con apposite strutture messe a disposizione dal linguaggio di scripting che si usa.

dynamic Web page
Web pages that respond to users' requests and gather information from them. Oftentimes, they have built-in links to a relational database, from which they extract data based on input from the user (using dynamic SQL). Dynamic Web pages contain very little actual text. Instead, they pull needed information from other applications. Dynamic Web pages communicate with databases to extract employee directory information, spreadsheets to display accounting figures, client-server database management systems to interact with order processing applications, and more. Because a database already exists, why re-create it for Web page publications?
