How to build SOA applications effectively?

Presenter: Dr. Hao He
Venue: Level 4,
122 Castlereagh Street,
Sydney 2000
Time: 6 pm - 7.30 pm

This talk explorers one approach that utilises XML pipes. With the right infrastructure, the author was able to build a full-featured online shop totally in XSLT. This new architecture will be contrasted against a traditional 3-tier architecture. A quick implementation walk through will also be given.

Topic: Interoperability Challenges in Service-Oriented Architectures
Presenter: Dr. Boualem Benatallah (Senior Lecturer UNSW)

Venue: Level 4,
122 Castlereagh Street,
Sydney 2000
Time: 6 pm - 7.30 pm

The emerging next-generation Web technologies, centred on the concept of Web services, promise to enable interactions and efficiencies that have not been experienced before. The foundation of this technology lies in the modularization and virtualization of system functions as services that:

1. can be described, advertised and discovered using (XML-based) standard languages, and
2. communicate through standard Internet protocols.

This talk examines some of the interoperability challenges in service-oriented architectures. While much progress has been made toward providing basic interoperability at the communication layer, there is still a lot to be done. Interoperability is more pronounced in service-oriented architectures than usual partly because services are typically developed by different organizations, and the difficulties created by services' autonomy and heterogeneity. We highlight interoperability aspects at higher level of abstractions including content and business process layers. Finally, we will discuss several open research issues in facilitating large-scale interoperation among Web services.
