The Common Data Access API is used by viewer-like applications (e.g., Visualize) to access structural information and object properties of imported (open) databases. The structure is provided as a tree, where the nodes of the tree are connected with imported graphics via a unique ID. Specific levels of the hierarchy in the tree depend on the domain, as well as the connection of this perceived hierarchy with the database content. This provides users with a way to view drawing, model, and database files in a simplified, universal form. Obtaining this information is based on the RxProperties mechanism (Non-COM properties).

The functionality is implemented in the RxCommonDataAccess.tx module.
