Dynamic Content
"Dynamic" refers to actions that take place at the moment they are needed rather than in advance.
Dynamic content refers to content that is generated at the time a web page is requested by a client, in effect, when a user loads the page in their browser window.
Dynamic content implies that the viewable content (of the web page, Flash presentation, etc.) can change without the actual source code for the page/application itself being edited or recompiled.
Programming within the host page or application is what allows for this change in content presentation. It may be achieved through a variety of means, such as the inclusion of any (or a combination of) the following infrastructure/elements: cookies, JavaScript, CSS, Flash, Java, PHP, ASP, Director Shockwave, databases, SSI, CGI, ActiveX.
Examples can range from very simple to very sophisticated.
A very simple example is a rollover effect applied to either text or graphics: a visual change is effected by a mouse interaction. This example is so simple, however, it is taken for granted.
A more typical example is that of database-driven web sites, in which web page content is drawn from a database instead of residing (hard-coded) on the source code for the page. In this case, updates to the database content directly affect the web pages, and result in the updates to the web pages since their content is linked to the database contents.
Significant to the maintenance of a web site, database-driven sites may be designed such that content for most or all key components of the site are linked to a database. Thus, for example, an addition of a new web page might not just result in availability of the new page, but in its proper incorporation in relevant indices, navigational menus, the site map, etc.
