A Ruby gem for Rails that lets you run data migrations alongside schema migrations. Data migrations live in db/data and are tracked in a data_migrations table, mirroring Rails' standard schema migration workflow.

Use cases

• backfill or transform existing records when deploying schema changes
• titleize all existing titles in a database
• run data updates in production separately from schema migrations
• track which data migrations have already run
• generate data migrations like regular Rails migrations

When to choose

• you have a Rails app with ActiveRecord and need to change data as part of a migration
• you want data changes versioned and tracked like schema migrations
• you need separate rake tasks for data-only migrations in production

When to avoid

• you are not using Rails or ActiveRecord
• you only need schema migrations, which Rails already handles
• you need migrations for non-Ruby databases or ETL pipelines
