Abstract. The DynaQuest-Framework should reduce the effort for the
creation of Internet-based virtual databases. These virtual databases are
a special kind of federated database systems where the sources are no
fully-fledged databases with a query language but rather simple and re-
stricted data provider, like web-form-based sources ("hidden web") or
web services.
To support the development of these systems, DynaQuest concerns four
different aspects: a source description format, a source selection process, a
query execution and monitoring framework to execute queries, and finally
an agent based architecture with integrates the different components of
DynaQuest.
1 Introduction
A common way to integrate data sources from a distributed, heterogeneous and
dynamic network like the Internet is the mediator/wrapper-approach [2]. Source
