It isn't easy (perhaps not even possible) to get the name of the fruit Bob grows in his farm using any of these tools and the following data:

  {
    "models": [{
      "title": "fruits",
      "fields": [
        {"name": "Name", "key": "3746"},
        {"name": "Colour", "key": "4867"}
      ],
      "entities": [{
        "_id": "372612",
        "3746": "Orange",
        "4867": "orange"
      }]
    }, {
      "title": "farmers",
      "fields": [
        {"name": "Full name", "key": "8367"},
        {"name": "Address", "key": "3947"},
        {"name": "Fruits", "key": "5243"}
      ],
      "entities": [{
        "_id": "747463",
        "8367": "Bob, the farmer",
        "3947": "Farmland",
        "5243": ["372612"]
      }]
    }]
  }
