A data model represents a precise information landscape, and there are different levels of modeling depending on the audience and the model’s purpose. A conceptual data model (CDM) is the highest-level of modeling and is designed to capture business needs and help both business and IT professionals agree on a common set of terms and definitions. It is an extremely powerful data model and this video will not only explain the CDM, but also work with you on a hands-on exercise covering the five steps for creating a CDM. Learn why the CDM is so important and see several actual CDMs and learn how each was built.
This video was recorded live during Steve Hoberman's Data Modeling Master Class. More on this 3-day data modeling course at stevehoberman.com.
