Secure Web Services – How to Do It, and at What Cost

Web services is steadily gaining momentum as a means of business to business integration. One of the main issues around this type of integration has been security, both with regard to content integrity and with respect to authentication/authorization. In this session we go through how you would go about solving these issues, using techniques such as secure HTTP and Web Service Security (WSS). We also look at what the cost is of doing integration with secure Web services as opposed to other more traditional ways of integration, learning from a real life project. At the end of this session you should be well prepared to decide whether or not you should go ahead with a Web services project and how to do it yourself, having learned how to avoid the common pitfalls.

Model Driven Architecture (MDA) – A New Paradigm in Software Development

Model Driven Architecture, from the Object Management Group, promises to be a new paradigm in software development, with the major goal of separating business and application logic from the actual platform specific implementation. In this session we will go through the various parts that make up the MDA, being the Platform Independent Model (PIM) , the Platform Specific Model (PSM), Interface Definition Sets and the transformation between the PIM and the PSM, and between the PSM and the code using artifacts as Object Construction Language (OCL). We also take a look a what options you have for doing work with the MDA, using both open-source and commercial tools. At the end of this session you should be able to decide how to proceed with MDA.
