107 ;;Quote: an information system depends on accurate, consistent data; constraints defined as part of the databases schema
108 ;;Quote: in conceptual modeling, all information as objects which are related by attributes
108 ;;Quote: information objects have an identity independent of their structure or attributes
108 ;;Quote: similar objects grouped by classes which prescribe common attributes and constraints
108 ;;Quote: object classes organized in a hierarchy with inheritance of constraints
110 ;;Quote: a database schema needs a consistent definition of all terms; does not exist, so use exceptions
110 ;;Quote: have exceptional facts which deviate from the schema's constraints
110 ;;Quote: have exceptional subclasses which contradict portions of their superclass definition
111 ;;Quote: allowing exceptional instances can destroy type-safeness; e.g., using Canadian dollars instead of U.S. ones
113 ;;Quote: handle exceptional subclasses and instances by exception handling triggered by the exceptional data
114 ;;Quote: an exception handler defines interpreted extensions to handle variants and exceptional data
