Data structure

The overall data are classified into global static and model data.

Global static data are shared by all models and each model has its own drawing and object data.

Global static data are shared by all models in a given database.

Two particular static data types (component and property) are referenced from more than one place in the data model. They are referenced both by global static data and by static data definitions within individual objects. They are referenced using a combination of name and tag name.
