Just wanted to announce a series of articles which are now posted online.
1. Agile Data Modeling: Part 1 of 3
(http://www.sdmagazine.com/documents/s=9314/sdm0409k/sdm0409k.html). This
article works through an example showing how to take an agile approach to
data modeling, working through three iterations of the physical data model
for a business application.

2. The Schema Evolves: Agile Data Modeling Part 2 of 3
(http://www.sdmagazine.com/documents/s=9224/sdm0408i/sdm0408i.html). This
article continues the case study from part 1, working through two more
iterations of the data model and exploring the implications of taking an
agile approach to database development.

3. The New Rules: Agile Data Modeling Part 3 of 3.
(http://www.sdmagazine.com/documents/s=9314/sdm0409k/sdm0409k.html). This
article explores the impact of a major refactoring to the database schema
and provides advice for data professionals who wish to become more agile in
their approach.

4. Agile Data Modeling: From Domain to Physical Modeling
(http://www.agiledata.org/essays/agileDataModeling.html). This essay
examines the same case study as the articles in Software Development do but
goes at it from a different approach, starting with a slim domain model on
which both the object schema and data schema would be based. The resulting
physical data models are different in the early iterations but soon
converge. The differences and implications are interesting.
