Job Description

 
The Business Modeler is responsible for transforming business information into models (most often logical data models) and managing the enterprise data model. The emphasis on this position is the “modeling of the business” that is required for a successful data warehouse. This goes beyond the role of a typical application level “data modeler” in that it requires modeling from an “enterprise perspective” rather than from a single business function perspective. The Business Modeler is proficient in industry standard techniques for process modeling and data modeling. Within data modeling, the Business Modeler must be proficient in 3rd normal form relational modeling. Dimensional modeling experience would be a strong added value for online analytical processing. This role must be experienced in group facilitation with participants from diverse business functions and work skills. The Business Modeler may be the Lead Consultant on a project. The Business Modeler is responsible for the design and instantiation of the physical data model, based on the logical data model. This includes creating the base tables, associative tables, and views, and choosing and creating all indexes.
