title: Ideal database choice for storing Wearable data (Fitbit)
body: <p>I'm recently developing an app on Fitbit.
  I am considering MongoDB or HBase as it has support for aggregation and support for processing data in Key value format.
  Example dataset:</p>
  
  <pre><code>{
      "activities-heart": [
          {
              "customHeartRateZones": [],
              "dateTime": "today",
              "heartRateZones": [
                  {
                      "caloriesOut": 2.3246,
                      "max": 94,
                      "min": 30,
                      "minutes": 2,
                      "name": "Out of Range"
                  },
                  {
                      "caloriesOut": 0,
                      "max": 132,
                      "min": 94,
                      "minutes": 0,
                      "name": "Fat Burn"
                  },
                  {
                      "caloriesOut": 0,
                      "max": 160,
                      "min": 132,
                      "minutes": 0,
                      "name": "Cardio"
                  },
                  {
                      "caloriesOut": 0,
                      "max": 220,
                      "min": 160,
                      "minutes": 0,
                      "name": "Peak"
                  }
              ],
              "value": "64.2"
          }
      ],
      "activities-heart-intraday": {
          "dataset": [
              {
                  "time": "00:00:00",
                  "value": 64
              },
              {
                  "time": "00:00:10",
                  "value": 63
              },
              {
                  "time": "00:00:20",
                  "value": 64
              },
              {
                  "time": "00:00:30",
                  "value": 65
              },
              {
                  "time": "00:00:45",
                  "value": 65
              }
          ],
          "datasetInterval": 1,
          "datasetType": "second"
      }
  }

  <p>What would be an ideal choice to database to store the Sensor data as I wish to do analysis on this data in my application?
  Thanks!</p>
