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.
The LDM is tied to the workspace. Within a workspace hierarchy, the LDM of a parent workspace is shared with the child workspaces.
In GoodData, you work with the LDM in the LDM Modeler.
