Declarative Specification of Data-intensive Web sites

Abstract
Integrated information systems are often realized as
data-intensive Web sites, which
integrate data
from multiple data sources. We present a system, called Strudel, for specifying and generating
data-intensive Web sites.
Strudel separates the tasks of accessing and
integrating a site's data sources,
building its structure, and generating its HTML representation.
Strudel's declarative query language, called
StruQL,
supports the first two tasks.
Unlike ad-hoc database queries, a StruQL query
is a software artifact that must be extensible and reusable.
To support more modular and reusable site-definition queries,
we extend StruQL with functions and describe how
the new language, FunStruQL, better supports common site-engineering
tasks,
such as choosing a strategy for generating the site's pages
dynamically and/or statically.
To substantiate Strudel's benefits, we describe
the re-engineering of a production Web site using FunStruQL and show
that the new site is smaller, more reusable,
and unlike the original site, can be analyzed and optimized.
