| No. Data Modelling is the process of designing a representation of information in any system - i.e. creating a model of that information.There are several tools and techniques that can be used. Entity Relationship Diagrams (ERDs) are just one way to make pictures of entity-based models. There are also fact-based modelling techniques such as Object-Role Modelling (ORM) that use different types of diagrams. Another alternative is UML (Unified Modelling Language).A good data architect should be familiar with a range of tools and techniques. From conceptual models like the Zachman Framework and ORM to more "bottom-up" design techniques like dependency theory and normalization. |
