Using Oracle DB 12c (12.2.0.2) and have a DB called "glddb" that was created a very long time ago using Oracle's SQL Developer Data Modeler tool. I have a lot of experience using the old Oracle Designer where we could easily compare a schema to a data model resident in the repository of Oracle Designer. We are using Oralce SQL Developer Data Modeler v 4.1.1.888. I would like to know how to do the exact same thing using the Data Modeler tool of SQL Developer where I could run a 'COMPARE' between my relational model (I'll call it Repo") resident in the tool itself against an existing DB schema called "glddb" that is in use by our team. This way I could determine if we are keeping both the repository and DB in sync.
