------------------------------------------------------------------------------
- The RDB DAS allows clients to receive data graphs composed of dynamic !DataObjects or, alternatively,
static !DataObjects.  Unless otherwise specified, the DAS will return a graph of dynamic !DataObjects
(see ResultSetDrivenDataObjectTypes).
+ Although the default behavior is for the RDB DAS to produce graphs of dynamic !DataObjects
(see ResultSetDrivenDataObjectTypes), the DAS allows users to work with Static !DataObjects
as well.
  
- Clients can designate a set of Types by providing a piece of configuration (usually in the
form of a configuration XML file) to the DAS And, when this is the case, the DAS will use
these Types for the !DataObject model. 
+ Clients can designate a set of Types by providing a piece of configuration (usually in the
form of a configuration XML file) to the DAS and the DAS will then use these Types for the
!DataObject model. 
  
  Without any configuration specified, the DAS will attempt to use !DataObject Type and Property
names equivalent to database Table and Column names. For example, if the database table name
is "BANK_EMPLOYEE", the DAS will attempt to create !DataObject instances of type BANK_EMPLOYEE.
If this Type doesn't exist in the provided Types, an exception will be thrown by SDO.
