##  The GRAPH table is used to store graphical information about items that#  appear in maps.##  _rowid       is a positive integer, unique within the GRAPH table, that#		is used to identify a specific row in the table.##  created      is the date and time that the row entry was created##  modified     is the date and time that the row entry was last modified##  map		is the rowid of the MAP table entry that this GRAPH entry #		applies to.##  type		is the type of this entry.  Current types are #               GXSNMP_MAP_HOST, GXSNMP_MAP_NETWORK, and GXSNMP_MAP_WIRE.##  host         For GXSNMP_MAP_HOST and GXSNMP_MAP_WIRE entries, contains#               the rowid of the associated host entry.# #  network      for GXSNMP_MAP_NETWORK and GXSNMP_MAP_WIRE entries, contains#               the rowid of the associated network entry.# #  details      is a method-specific description of all information#               needed to display the item, such as X and Y locations,  #               pixmap names, etc.  The field is in gtkrc format.##  x and y      are temporary columns, because the code to read and write #		the display field isn't written yet.##  pixmap	is the pixmap filename to be used when displaying this#		object.##  tags         is the application specific tags for this object.#create table graph (   _rowid        int not null,   created      char(20),    modified     char(20),   map		int,   type 	smallint,   host         int,   network	int,   details	char(255),   x		double precision,   y		double precision,   pixmap	char(255),   tags         char(255),   primary key  (_rowid),   foreign key  (map)     references map,   foreign key  (host)    references host,   foreign key  (network) references network );
