Why use a dependency file?
If used on its own, a dependency file provides better performance performance due to the reduction in round-trips to the database. In most cases performance is not a good enough reason to choose to use a dependency file since developers must maintain the file along with the schema. The main reason to use a dependency file is for situations where the JDBC driver you are using is broken in some way and the information retrieved from the JDBC driver cannot be relied upon or causes Sqlch to fail. The dependency file can be used as either an alternative from the dependencies reported by the database or to provide additional dependency information.
