Six Jumpstart Lessons About Visual Modeling

relationship symbols

• We need to take this slowly for each relationship symbol.

• Three representations:

  • terms / meanings
  • ascii symbols
  • diagrams

• Note that when relationships are reversible, we can show that...

• 'One : Many' = --<

  • 'Many : One' = >--

• 'Class : Types' = --E

  • 'Types : Class' = 3--

• Examples

  • Sessions --< Messages
  • People --< Opinions --E
  • Fun --E
