We focus on the problem of data transformations, i.e., how to
transform data to another structure to adapt it to new application
requirements or given environments. Here, we define data transformation
as the process of taking as input two schemas A and B
and an instance of A, and producing an instance of B. Today, data
transformations are required in many situations: to integrate multiple
information sources, to construct and receive data for Web
services, and to migrate data from legacy systems to new systems,
from local databases to data warehouses. This demonstration focuses
on XML transformations, since XML is the de facto standard
for data exchange.
