This package provides type classes to allow backends to implement SQL DDL support for beam. This allows you to use beam syntax to write type-safe schema generation code.

The package also provides features to introspect beam schemas, and support for automatic generation of migrations in SQL and Haskell formats.

This is mostly a low-level support library. Most often, this library is used to write tooling to support DDL manipulation in your project, or to enable migrations support in beam backends.
