Class Schema

java.lang.Object

org.hrorm.Schema

public class Schema
extends Object

The Schema class can be used to generate SQL to create tables, sequences, and constraints described by DaoDescriptor objects.

The SQL generated is perhaps not ideal. It uses lowest-common denominator like "text" and "integer" and databases have more precise types that should probably be preferred.
