Enterprise Data Model Infographic: For companies that value their data
Enterprise Data Model is an integrated view of the data produced and consumed across an entire organization. EDM is the foundation of all other kinds of data systems, which can be implemented in the organization.
The model has three separate levels: Subject Area Model, Conceptual Model, and Conceptual Entity Model, as every level is more detailed than the previous one.
On level One, the data is broken into subject areas, divided as Revenue, Operation, and Support. Each of those areas is defined with transactional, foundational, and informational data.
On level Two, based on the main business practices of the organization, major business concepts are being identified and linked to each of the defined areas in level one.
On level three, the identified concepts are recognized as important to the business entity, looking at company needs, understanding of business terms, defining additional details, and recognizing the relationship between the concepts.
