Autodesk Forge: What is the difference between dbId, objectId, and nodeId?

问题

What is the difference between dbId, objectId, and nodeId?
For example, the first argument of the following functions is the same kind of id or ids?

• fitToView(objectIds,model)
  objectIds: array of Ids, or null.

• getProperties(dbId,onSuccessCallback,onErrorCallback)
  dbId: ID of the node to return the properties for.

• select(dbids,selectionType)
  dbids: You can pass an array of IDs or just a single ID.

• hideById(nodeId)
  nodeId: (no description)

from Viewer API reference here

It's actually the same, just some discrepancies about the doc.
