Logical Data Model
A logical data model (LDM) is an abstract view of your data in GoodData. The LDM is a set of logical objects (datasets and Date datasets) and their relationships that represent the data objects and their relationships in your database through the physical data model (PDM). The LDM is connected to and is based on the PDM.
In GoodData, you work with the LDM in the LDM Modeler.
