dbmigrations is: A library and program for the creation, management, and installation of schema updates (called migrations) for a relational database. In particular, this package lets the migration author express explicit dependencies between migrations and the management tool automatically installs or reverts migrations accordingly, using transactions for safety. This package is written to support any HDBC-supported database, although at present only PostgreSQL is fully supported. To get started, see the included README and MOO.TXT files and the usage output for the "moo" command. Get it from Hackage: http://hackage.haskell.org/package/dbmigrations Or get the source with darcs: http://repos.codevine.org/dbmigrations/ This package is motivated by the need for a framework-independent, solid tool to manage database schema changes in a clean way without assuming a linear sequence of changes assumed by existing tools. dbmigrations lets you manage a forest of schema changes. Future work will include an hscurses-based tool to visualize and manipulate available migrations and their dependencies and support for other database engines. Please don't hesitate to send patches, feedback, and criticism directly to me at drcygnus AT gmail DOT com. I'd like to say thanks to Josh Hoyt and Jason Dagit for suggesting improvements, providing support, and showing me how beautiful Haskell is. Thanks! Enjoy! -- Jonathan Daugherty
