In another article, we described how a data object may have a related geopoint (or a collection of geopoints). One of the benefits of data-to-geo relationships is search by distance. That means Backendless can search for data objects using the location of the related geopoints.
Connecting users with their related data is a key function of user management. When you register (or update) a user object, you may need to create a relation between the user and some other entity/object stored in your Backendless Database. Since a user object is structurally a collection of properties, it is very easy to…
In another post, we described how to obtain a file’s public URL using Backendless Console. Even though anyone can obtain a public URL for a file or directory, it is very easy to change the permissions to restrict file download for anonymous (not authenticated) users.
In other articles, we have covered: how to declare a geo-to-data relationship in a data table schema and how to create relationships between an object in that schema and geopoints. Of course, both of the operations above can also be accomplished with the API. In this post, we are going to show how to retrieve…
In another article, we covered importing data table schemas, relations and data objects to Backendless with CSV files. The data import feature can also work with geolocation storage. The process is extremely simple – browse to a CSV file with the geolocation data and let Backendless process it.
In another article discussing user management, we covered how to use the user registration API to register users for your app. When registering a user, your app sends a collection of user registration properties to the server. Values for these properties typically come from a registration form in your app. Some form fields may be…
Any file in the Backendless File Storage is also accessible through a public URL. This functionality can be restricted by changing security settings.
In another post, we introduced you to the publish/subscribe messaging API. The API can be used to broadcast messages that can be received by multiple client apps. Note: It is important to distinguish between pub/sub messages and Push Notification messages. There are a number of technical differences and purposes where an app should use one…
In other articles, we have reviewed multiple techniques for loading data objects from persistent server-side storage. There is a list of all articles categorized by topic. In this post, we are going to review the API for loading data objects using an SQL query.
