Mongodb
I'm using mongodb as my database. I have an record of 100 hospitals. To store all the information i'm designing schema of my database for that i've three solutions:
i can create collection for each hospital and store data in it.
Problem: i need to fetch records from all the hospital at once so i think it is very complex.
I can create only one collection and create hospital wise embedded document in it.
Problem: document size grows but document is limited in size.For a particular query need to read all documents.
I can create only one collection and add a information like hospital id in it.
Problem: collection size increases. For a particular query need to read all documents.
Please tell me which one is better solution from them. If any other solution is possible please tell me.
