Rules and Guidelines for Entity Relationships

The Designer generates entities based on the following guidelines:

An entity represents a portion of an XML, DTD, or XML schema hierarchy. This hierarchy does not need to start at the root of the XML file.

The Designer uses entities defined in a DTD file to create entity relationships.

The Designer uses type structures defined in an XML schema to generate entity relationships.

The Designer creates a new entity when it encounters a multiple-occurring element under a parent element.

The Designer generates a separate view for each member of a substitution group.

The Designer generates primary keys and foreign keys to relate separate entities.
