All schema artifacts will be compared (tables, indexes, procedures, packages, sequences and, functions). In the use case described here there are two Oracle database schemas compared, one in DEV and the other in TEST. This topic is not a comparison of SQL Developer/JDeveloper to schema migration tools like Liquibase and Flyway but instead, a quick tutorial on leveraging this widely adopted Oracle tool for the list of schema differences. SQL Developer/JDeveloper will do this quickly and effectively.

However, there are times when you simply want to list the differences between two schemas quickly, producing a "Diff Report" and optionally to create the SQL to show the alters necessary to upgrade the destination schema. Undoubtedly for large database schema installations commercial schema migration tools like Liquibase or Flyway makes sense. The tools provide a database agnostic means to do this and to perform schema rollbacks if necessary. The tools provide a very controlled means of migrating schema changes from DEV to TEST and to PROD, the goal to preserve the underlying data. Liquibase by Datica and Flyway by Boxfuse are two such commercial tools.
