Loading data objects from the Backendless persistent storage is a fundamental operation a large majority of the online/mobile applications require. Backendless Data Retrieval API is simple, yet very powerful.
In other articles, we’ve discussed how to load object relations using the auto-load and the one-step approach. Both of these approaches return a complex hierarchy of data where the parent object includes child entities at the time when it is retrieved from the server.
In another article, we described how to load complex data objects from the persistent storage using the “auto-load” technique. Using that approach, a developer can statically identify specific (child) properties that should be returned along with the parent object(s) when a client app sends a request to load them.
Another post covered how to retrieve data objects from Backendless.

Flutter is a new cross-platform frontend framework from Google. In this article, we are going to show how to set up push notifications for your Flutter project and how to handle notifications directly from Flutter.
In this series of articles, we are going to show you how to make a beautiful chat app that supports sending, editing, and deleting messages with both text and images.
In another post, we describe how data tables in Backendless map to the client-side classes whose instances contain persisted data objects. However, there are scenarios when the default mapping is undesirable. In that case, Backendless client libraries provide an API to override the mapping.
