In SSDT there is a mechanism for managing DDL changes, for instance a new column or a change to a data type. Instead of putting an 'Alter Table' statement into the database project, instead we edit that original 'Create Table' statement which focuses on the final state that includes the new column. It detects the difference between older and new script and creates necessary 'Alter Table' script to use for deployment.
Is there any equivalent strategy to achieve the same in Oracle Database as I am using J2EE technologies and Eclipse IDE.
