In this Episode, Eberhard and Markus provide an introduction to Model-Driven Software Development. Since the discussion turned out to be too long, we separated things into two episodes, thus Episode 6 will be the second part of this discussion. In this first part we disucsss core concepts of MDSD, the relationship to MDA, and hint at a couple of tools.

After discussing some of the more technical aspects of MDSD in the last episode, we take a look at other important topics in this one. This includes some tips on how to introduce MDSD into projects and how the development process has to be adapted for this to work, as well as a look at the return on investment for MDSD. The relationship of MDSD and Agile software development is also discussed. Finally, we take a look at offshoring in the context of MDSD.

In this episode Michael and our guest Prashant Jain talk about patterns for resource management. Efficient management of resources is critical in the execution of any kind of software. Ranging from embedded software in a mobile device to software in a large enterprise server, it is important that the resources, such as memory, threads, file handles, or network connections, are managed efficiently to allow the systems to function properly and effectively. Michael and Prashant discuss various patterns, such as Lazy Acquisition, Caching, Leasing and Evictor and explain when, why, and how to apply them for effective resource management.
