Assessment

Please use an existing user / loaded in LoadDatabase controller.

Warning - sample data structure is not exactly the same as requested. Explanation here below.

Sample data :

{"user":"[email protected]", "begin":"2019-07-01T09:47:46.000+0000", "end":"2019-07-01T10:47:46.000+0000", "data": { "heartRate":80.0 , "someOtherMeasure":70.0 , "anotherMeasure":50.0 }

}

NOTE - data key/value change

The original required data structure was a 'List of objects' with key / value but without unique key integrity.

[{ "heartRate":80 },{ "someOtherMeasure":70 },{ "anotherMeasure":50 }]

However, my understanding was the followings :

A session retrieves a collection of values. 1 key of 1 session has only 1 value (?)

As I cant ask about that understanding issue, I took the decision to propose a change to a slighly different interface with a hashMap. My understanding is that is more sounds aligned with the description.

The resulting implementation describes my understanding of the situation : a Hashmap of key/value stream linked to a Session.

{ "heartRate":80.0 , "someOtherMeasure":70.0 , "anotherMeasure":50.0 }
