  2. Tables involving the Map • Map_Table The map of the “world” • User_Location_Table A user’s location at a particular instant in time • Building_Table A table with building names and descriptions

  3. Building Table This table is a list of all the buildings in the world Fields • Building_id – integer given to building (primary key) • BuildingName – string “Engineering Building” • Building description – string describing each building

  4. The primary key is composed of these four fields: X - an integer representing the x coordinate Y - an integer representing the y coordinate Floor - an integer representing the floor BuildingID – an integer; the ID of the building Room - string e.g “Classroom” Description – a string a description of the room Map Table - Fields
