How it is work inside?

1. First, get list of all user_object to export

select * from user_objects

1. then applying dbms_metadata.set_transform_param
2. for every user object invoke dbms_metadata.get_ddl and dbms_metadata.get_dependent_ddl
3. print every ddl to separate file grouped in folders like tables, views, procedures etc

scheme2ddl build on top of spring-batch framework.
