Episode 87: Software Components
In this episode, Michael and Markus talk about software components. We first looked at a couple of attempts at defining what a component is. We then provided our own definition that will be used in the rest of the episode. We then looked at the promises of component-based development: why are components useful?
We then discussed some of the typical metadata components should specify to make them useful. We discussed to some extent typical variations in component models. The next topic was the separation of concerns between the component functionality and functionality provided by the component’s execution environment (aka. container).
We then compared components with other (more or less) related technologies such as OO and SOA.
We concluded the episode with the notion of architecture as language, where you use a formal DSL to describe a system’s architecture. Components are the basic building block for this approach.
Episode 33: Service Oriented Architecture, Pt.2b
This is the second snippet of the SOA 2 double-episode. Eberhard and Markus continue the discussion with the issue of service reuse and a couple of development process issues. We also look at the duality between infrastructure development and application development in the context of an SOA. We then discuss the great spaghetti misunderstanding :-). We conclude this episode with a look at how to integrate BPM into the conceptual SOA framework we’ve built up to now, and we’ll also briefly skim over a number of technologies related to SOA.
Note that this episode, as well as the last one, is based on a set of slides; these can be downloaded from here. This episode covers slides 39 through 74.
