Characteristics: The typical progression consists of the following stages: Theres no fixed number of use cases that translators must complete at each stage to progress their abilities. Yet it is all too common for executives to assume that employees can act as effective translators, capable of delivering analytics solutions, once they complete a class on the rudiments of modeling. A relational database is a single data repository that provides both structural and data independence while maintaining conceptual simplicity. Using the ER diagram, it's easy to map the ERM to the relational database model's tables and attributes.
