Example
6
ESRI DM for water supply networks

• Features are spatial entities that do not
  participate in the active network
• Equipment are the features in a water or
  wastewater system that do not have an associated
  geometry or position

7
ESRI DM for water supply networks

• Facilities are used in transmission and
  distribution of water and are commonly used to
  join various water lines together  
• The assorted types of pipes used in the
  transmission and distribution of water are
  generically termed lines

ESRI DM for electricity networks

• Structure is the abstract class that contains
  common characteristics, or attributes, for all
  electric structures involved in the distribution
  or transmission of electricity
• Electric devices help ensure consistent service
  within the distribution network

40
ESRI DM for electricity networks

• Circuit segments contain classes and properties
  that describe the conductors that transmit and
  distribute electric current
• Customer and service objects contain customer
  information and information about generators of
  alternate sources of electricity
