Adding Data in Firebase Database

Question

I am migrating to Firebase to help me retrieve my data. My question is how can I format my Firebase Database data like the JSON below. How can I specify objects like the JSON below?

Answer 1

You can write pretty much any JSON you'd like directly to Firebase. For ease of retrieval though, you'd need to figure out some sort of schema. I'd recommend something like the following:

doctors
  <docotrId>
    - doctorId
    - doctorName
    - specialisation
    - information
    - photo
    - phone
    - email
    - @healthCenter
healthCenters
  <healthCenterId>
    - centerId
    - name
    - @doctors[]
specialisationDoctors
  <specialisationName>
    <doctorId>

The first thing you need to do is map your data to this schema. You can create POJO classes, Maps, or even JSON formatted strings.

Then push your mapped data using setValue() on the appropriate nodes. Make sure to read the documentation for more information.

You might also want to check out a Firebase object mapper I'm working on called Firebomb (shameless plug). The Android version will be coming soon.

Finally retrieve data by using the appropriate Firebase event listeners.
