Version: GeneXus 18

Backend Development

Modules and external objects

The concept of modules is introduced, which allow us to group objects from our KB in order to encapsulate functionalities, facilitate their maintenance and integrate them with other KBs. We will also see what external objects are, which allow us to access resources external to our KB and work with them as if they were just another KB object.

Presentation

Even though GeneXus allows us to generate End-to-End applications—that is to say, it generates the front end, the back end, and the database—the implementation of increasingly complex digital systems makes it necessary for developers to know and specialize in the different parts that make up the systems. 
 
Back-end developers work on the implementation of objects that contain the logic of an application running on the server, as well as data storage, development of interfaces to interact with the application (APIs), integration with other systems through web services, invocation of remote procedures (RPC), import of binaries, structured data (JSON or XML) and other resources, architecture and development of components that consume and publish services (such as SOA or microservices implementation), interaction with data from different databases or repositories, and other server-side functions.
