It is based on a server side architecture. Serverside is PHP/mySQL, available clients are in ant, Java and bash scripts. It is productively used by companies in Switzerland and India. I would be interested in your comments. hi, there is also http://www.deltasql.org as an Open Source tool to mantain incremental changes to databases. It is based on a server side architecture.

First look, it looks a bit like DBDeploy. Also check out this blog: http://exortech.com/blog/2009/02/01/weekly-release-blog-11-zero-downtime-database-deployment/ If using migrations and always keeping backwards compatibility for a while, you can actually test a new version of the application in production before "committing" to it. Intriguing. :) Found a new tool at http://code.google.com/p/bering/ . First look, it looks a bit like DBDeploy.

That would be a good option for a new Ant task or the deployer. I guess they're not available in any Maven repo though. :( Cool. That would be a good option for a new Ant task or the deployer.

Maven was already installed. But that's really no biggie. I think the stuff you are saying makes sense. Just a couple of things that would make everything ideal: * All artifacts for deploy to anything else than local dev is available in central Maven repo. Even with cargo plugin. * Have separate tasks that lets you create/copy/dump databases easily for everyone. I think you probably have most of it covered, and as I say it would just make everything ideal. :) When it comes to Sqlplus vs. Ant it was just a question of which operations are available through JDBC. When you're doing some more advanced DB refactorings you might need some of the Sqlplus features. But there's really no problem using Ant sql until you need the sqlplus stuff. Just make sure none of your developers grinds to a halt because they don't know what to do when they hit the limit of JDBC operations. :) My reason earlier for not using Ant from the command line was to avoid having the developers as well as host machines install it.

In dev-env use c5-db-migration to create migration scripts and to reset/create and migrate a database by utilizing the maven goals. 2. In test/stage/prod/etc run the migration scripts using Ant. The migration scripts will be bundled with the installer which is made by the maven-assembly-plugin. What do you think? This will give the developer the same tool (=Maven) for building code (maven-compile-plugin, maven-war-plugin, maven-ear-plugin etc) database-related tasks (c5-db-migration) deploying to appserver (maven-cargo-plugin) while reusing the same migration scripts in all other environments. Question: You've said in another post that you preferred Sqlplus over Ant SQL tasks. Could you tell me more about the reasons for this? Does SqlPlus/Ant SQL tasks have a way to specify the order to run the migration scripts created by c5-db-migration? I’m thinking about the following approach for solving my db-related tasks:
