Backendless is perhaps the most powerful and versatile visual database on the market. Not only that, but Backendless Database is the only visual no-code database that offers relational data. But if you have 1-to-1 data relations, don’t you want to see what the related object is? Now you can!
Backendless can create tables when you store object hierarchies from a client application. Also, we described how to manually create data tables using Backendless Console.
In another post, we describe how to add columns/properties to a Backendless table/class using Backendless Console. The types of properties reviewed in that post were all primitive: string, numbers, dates or boolean values. In addition to these data types, Backendless also supports relationships between objects stored in its persistent storage.
Previously we showed how to declare relationships between tables. Once a relationship is in place, specific objects stored in the tables may be linked with each other.
Data objects in Backendless can be connected to related properties not only in other tables, but also with Geopoints. These relationships may be declared programmatically or using Backendless Console. In this post, we will review the process of declaring a Data-to-Geo relationship in a data table schema.
In another post, we described how to declare a relationship in a data table schema with a geopoint. Now that you know how to create a table column that contains one or more geopoints, we are going to show how to populate it with data.
In this post, we will show how to save an object with relations in Backendless Database. We are using the “code first” approach, which means we will not be creating data tables in the backend. Instead, the code will dictate to the backend what the data schema should look like.
I am very happy to report that we released a new version of Backendless. The new release is tagged as version 1.9.0, which is a new numbering scheme for us – we used to label releases with names attached to various events. The new release is packed with features, improvements and bug fixes. I’d like…
Establishing relations between user objects and other entities in an application is a very common use case. This post describes various scenarios and shows sample code using Backendless SDK for Java/Android and Backendless SDK for iOS. Make sure the version of the client libraries are at least 1.5 for Backendless Java/Android and 1.11 for iOS.
