Introduction to essays toward a steady-state economy

My guess is that in the near term database TDD, or perhaps Test Driven Database Design (TDDD), won't work as smoothly as application TDD. The first challenge is tool support. Although unit-testing tools, such as DBUnit , are now available they are still an emerging technology at the time of this writing. Some DBAs are improving the quality of the testing they doing, but I haven’t yet seen anyone take a TDD approach to database development. One challenge is that  unit testing tools are still not well accepted within the data community, although that is changing, so my expectation is that over the next few years database TDD will grow. Second, the concept of evolutionary development is new to many data professionals and as a result the motivation to take a TDD approach has yet to take hold.  This issue affects the nature of the tools available to data professionals – because a serial mindset still dominates within the traditional data community most tools do not support evolutionary development.  My hope is that tool vendors will catch on to this shift in paradigm, but my expectation is that we'll need to develop open source tools instead.  Third, my experience is that most people who do data-oriented work seem to prefer a model-driven, and not a test-driven approach.  One cause of this is likely because a test-driven approach hasn't been widely considered until now, another reason might be that many data professionals are likely visual thinkers and therefore prefer a modeling-driven approach.
