Database Reference
In-Depth Information
At the highest level, we have the Conceptual Data Model (CDM), which captures the satel-
lite view of the business solution. The CDM provides the context for and scope of the
Logical Data Model (LDM), which provides the detailed business solution. The LDM be-
comes the starting point for applying the impact of technology in the Physical Data Model
(PDM). The PDM represents the actual MongoDB database structures.
In addition to the conceptual, logical, and physical levels of detail, there are also two dif-
ferent modeling mindsets: relational and dimensional.
