Database schema management systems

A list:

• Squitch - ?
• DBIx::Class::Migration - verbose but powerful. Use dbic-migration alongside dbicdump
• DBIx::Migration - not the same as, or as good as DBIx::Class::Migration
• DBIx::Migration::Directories
• DBIx::Patcher (used at NAP)
• perl-Monorail - ?
• App::JESP - ?
• Migraine
• Mojolicious::Command::migration - thin wrapper for dbic-migration
• Database::Migrator
• SQL::Schema::Versioned
• mimi
• gh-ost - massive overkill for small apps

System maintenance

There is a reason we have a process of change control. It has become a dirty word in some departments, but the bare minimum is:

• making a change in the development environment
• testing it, preferably by more than one person/team
• packaging up the release and labeling it properly
• making a formal request to deploy it, including roll-back instructions

In addition, a precedent should never be set to fix something that another department has broken!
