This assessment has been done using android application written in Java, it uses Cloud Firestore database from firebase to store the data of yoga classes participants across batches.
Link : Android apk
The applications consists of two fragments(pages),
Home (screenshot 1): there is user registration form, which takes user inputs for registration, it accepts name, age, contact, and batch in which user tries to get registerd, batch is a dropdown menu here, by clicking it option of available batches pops up.
Dashboard (screenshot 2): Realtime details of available batches and their status is shown, After user registration one can see the numbers being updtaed of corresponding batch in Dashboard.
The database used here is Firestore. Similar to other NoSQL databases cloud firestore is also based on Collections and Document Structure. So basically there are two Collections with mentioned attributes
* Participants
* name
* age
* contact
* batch_id
* payment_status
* Batches
* timing
* capacity
* filled
Participants is a collection, it has documents as objects which contains basic data required for registration of user for yoga class. batch_id is id which is used to refernece to another collection called batches.
Batches is also a collection here, it has 4 documents or objects with id 0,1,2,3 referring to 4 batches which are in operation. Each batch as 3 attributes timing,capacity(denoting total capacity of batch) and filled(current occupancy of batch).
