Reminder: Agile Houston meeting tonight, with Pramod Sadalage
John D. Salch
All,
Don't forget, Agile Houston has a talk tonight, sponsored by PROS.
Title: Evolutionary Database Design
Speaker: Pramod Sadalage
Abstract:
"For years the norm for object
developers was to work in an evolutionary (iterative and incremental) manner
but for database
developers to work in a more serial manner. The predominance of evolutionary
development methodologies such as Extreme Programming (XP), Feature Driven Development
(FDD) make it clear that the two groups need to work in the same manner to be
productive as a team.
Pramod will present material from the 2007 Jolt Productivity Award winning book "Refactoring Databases : Evolutionary Database Design" on how to go about doing evolutionary database development, how to apply all the agile practices to database development and will talk about the following techniques:
· Database refactoring: Evolve an existing database schema a small bit at a time to improve the quality of its design without changing its semantics.
· Continuous Integration: Why not test you database creation and migration scripts as part of Continuous Integration and apply the same rigor to the database artifacts that you apply to the application code. You should fail the build when the developer/dba makes a mistake doing a database change.
· Evolutionary data modeling: Model the data aspects of a system iteratively and incrementally, just like all other aspects of a system, to ensure that the database schema evolves in step with the application code.
· Database regression testing: Ensure that the database schema actually works.
· Configuration management of database assets: Your data models, database tests, test data, and so on are important project artifacts which should be managed just like any other artifact.
· Database Schema Deployment: Ensure that the scripts used to build development environments are the exact same as the used in QA, UAT and production. Ensure deployment to production is not a surprise and not a project in itself.

About The Speaker:
Pramod Sadalage is a Author and Consultant for ThoughtWorks, an enterprise application development and integration company. He first pioneered the practices and processes of evolutionary database design and database refactoring in 1999 while working on a large J2EE application using the Extreme Programming (XP) methodology. Pramod writes and speaks about database administration on evolutionary projects, the adoption of evolutionary processes with regard to databases, and evolutionary practices impact upon database administration, in order to make it easy for everyone to use evolutionary design in regards to databases. When he is not working, you can find him spending time with his family and trying to improve his running .
Best regards,
John
