Wow, I would hate to be your DBA!Glenn SlavenSun, 04 Feb 2007 18:23:57 -0000http://blog.slaven.net.au/archives/2007/02/04/agile-and-sql-links/#comment-1279550It is much easier to rename a column when all you got is one production site, a testing site and a few development sites. In our case, changing a column would require<br><br>- Change a column in the table definition file<br>- Write an upgrade script and test it against trunk + 2 branches<br>- Rebuild the 2 release branches<br>- Test the new builds <br>- Get permission from clients who need the change about upgrading<br>- Push out the change across 60+ servers in the evenings<br>- Send the patches + upgrade instructions to clients who are not hosted with us<br>- Wait for the support calls in the morning when clients found some incompatibility :)<br><br>Around a week of work, and we are already trying to be as agile as possible :(<br><br>Moreover, I found when the development only involves micro-iterations, people are less likely to work on re-factoring and re-architecturing the code, which are usually necessary when you are looking at 5+ years into the project...ScottSun, 04 Feb 2007 17:56:47 -0000
