i have firebase database data so:

{     "city name" : {         "uniqueid" : {            "averagerating" : 1,            "createdby" : "somedood",            "latitude" : 1234,            "longitude" : 4321,            "name" : "best buy",            "ratingcount" : 1         },         "uniqueid" : {            "averagerating" : 3,            "createdby" : "somedood",            "latitude" : 1234,            "longitude" : 4321,            "name" : "indigo",            "ratingcount" : 1         },         "uniqueid" : {            "averagerating" : 3,            "createdby" : "somedood",            "latitude" : 1234,            "longitude" : 4321,            "name" : "catholic parish",            "ratingcount" : 1         },         "uniqueid" : {            "averagerating" : 2,            "createdby" : "somedood",            "latitude" : 1234,            "longitude" : 4321,            "name" : "mac's",            "ratingcount" : 1         },         "uniqueid" : {            "averagerating" : 2,            "createdby" : "somedood",            "latitude" : 1234,            "longitude" : 4321,            "name" : "school",            "ratingcount" : 1        },        "uniqueid" : {            "averagerating" : 4,            "createdby" : "somedood",            "latitude" : 1234,            "longitude" : 4321,            "name" : "church",            "ratingcount" : 1        },        "uniqueid" : {            "averagerating" : 4,            "createdby" : "somedood",            "latitude" : 1234,            "longitude" : 4321,            "name" : "mall",            "ratingcount" : 1         }     } }
