FireSharp Retrieval Concept about firesharp HOT 2 OPEN

any body available?

Hello @Zaid-Mirza,
Let me try to answer your question. FireBase approach is basically has two ideas of containing data:

1. One-directional, meaning that we actually nest the child objects under the parent.
2. Two-way relationships we basically duplicating some data.

First one has some underlying meaning: when some entity has access to specific node, it also has access to all its descendants. I mean it's not good or bad thing, developer should be aware of this behavior. Another point here is that if db has a millions of descendants for node we trying to retrieve from database, it can be painful :)

In a second approach we duplicating data but this is necessary. The idea is that you load some data you need and then go to related node and fetch additional information required for first fetch.

Here is the link that might be helpful for you : https://firebase.google.com/docs/database/web/structure-data

Hope i succeeded to get to the point :)
