In this episode we're talking to Anneke Kleppe about model-driven software development and language engineering. We start with her involvement in the creation of the Object Constraint Language (OCL) and discuss the intial expactations, actual experiences, and the place of OCL in the current day. From here, Anneke talks us through her take on the formative years of UML and MDA. From here, we expand to the realm of Domain-Specific Languages and Anneke discusses their place in software engineering in general and why we should expect DSLs in significant numbers to become a common sight.

In this episode, Michael Plöd is interviewed about Object-Relational Mapping technology. He talks about the common concepts, compares the range of different tools that go by this name, and goes into the design and architectural consequences of using an OR mapper.

The majority of hacker attacks (70 %) are directed at weaknesses that are the result of problems in the implementation and/or architecture of the application. This session shows how you can protect your web applications (J2EE or .NET) against these attacks. The session covers lots of practical examples and techniques for attack. Furthermore, it shows strategies for defense, including a "Secure Software Development Lifecycle". A "Live Hacking" demo rounds it out. This is a session recorded live at OOP 2009.
