Business Area Models describe functional business or subject areas found in many industries or developed for a specific industry.

Each Business Area Model is constructed from a common set of entities from the corresponding industry Enterprise Model, which insures that Business Area Models will have common keys, attributes and definitions throughout the data architecture.

Business Area Models expand upon the 'thumbnail' of business area data represented in the industry Enterprise Model and provide complete coverage for that subject.

Business Area Models contain the greatest level of detail and provide the lowest level of data granularity in the ADRM model hierarchy - while maintaining definitions consistent across the entire model suite.

Business Area Models provide a data architecture for business analysis and planning, applications design and development of data marts and the data warehouse.

This approach enables the organization to design top-down and propagate changes and new requirements consistently between models. As new information is added to a Business Area Model it can also be propagated to the Enterprise Model, Data Warehouse Model, Data Mart Model or application models.

Business Area Models are used in conjunction with the Enterprise Model to develop star schema data mart models. Having both the Enterprise Model and Business Area Models for reference facilitates consistent dimension design and a resulting data architecture that implementing conforming dimensions.
