Abstract: Data processing and integration on heterogeneous data sources often
require intensive human resources on coding, but applications developed for
this purpose are usually inflexible to fulfill dynamic business requirements.
To-date, the Web Service paradigm standardizes the programmatic interfaces for
application-to-application communication. It has gained a considerable momentum
as a means of facilitate processing and integrating heterogeneous data sources.
To take full advantage of Web Services, we proposed an approach in which all
operations and data sources are exposed as Web Services. Based on that
approach, a novel declarative scripting language called WSIPL (Web Services
Integration and Processing Language) is designed to drive the data integration
and processing tasks via Web Services in minimal programming efforts. The
reference architecture of a WSIPL system and implementation issues are
discussed. Industries deployed with this technology found that WSIPL can
successfully enhance their data integration and processing systems with higher
flexibility and efficiency.
