Collaboration-ready Data Management

• Store data using OAA Data Management

  • oaa_DbDeclare(icon(Id, X, Y, PictureType),  [shareable, callback(icon_change)])

• Separate code which changes data from results, using callback feature

  • NOT:
    { oaa_AddData(icon(hilton, 100, 100, hotel), []) map_Display(icon(hilton, 100, 100, hotel)) }
  • BUT:
    { oaa_AddData(icon(hilton, 100, 100, hotel), []) }
    icon_change(add, icon(Id, X, Y, Picture)) :- map_Display(icon(Id, X, Y, Picture)).
