Data Modeling is a skill that a Business Analyst should think about developing. If not building the diagram, at least the BA should know how to read and validate them. There are two types of models that are important for the Business Analyst to know about:
- Conceptual Model- to identify the existing and new tables
- Logical Data Model- to define the business model of the required data
Data modeling defines what things the business needs in order to operate. It also defines the relationships between those things and the facts which are needed to describe the key data elements.
