Rapid Application Development with OutSystems

By: Ricardo Pereira

Overview of this book

OutSystems is a software development platform that speeds up the build phase by abstracting code and making almost everything visual. This means replacing textual language with visual artifacts that avoid lexical errors and speed up code composition using accelerators and predefined templates. The book begins by walking you through the fundamentals of the technology, along with a general overview of end-to-end web and mobile software development. You'll learn how to configure your personal area in the cloud and use the OutSystems IDE to connect with it. The book then shows you how to build a web application based on the best architectural and developmental practices in the market, and takes the same approach for the mobile paradigm. As you advance, you'll find out how to develop the same application, and the great potential of reusing code from one paradigm in another and the symbiosis between them is showcased.The only application that'll differ from the application in the exercise is the one used in business process technology (BPT), with a focus on a common market use case. By the end of this OutSystems book, you'll be able to develop enterprise-level applications on the web and mobile, integrating them with third parties and other systems on the market. You'll also understand the concepts of performance, security, and software construction and be able to apply them effectively.

Summary

In this chapter, we learned how server-side logic works, the artifacts available, and how to combine them to obtain the intended behaviors from our actions.

We learned what Server Actions are, the concept of variables in the context of Server Actions, how to create logic in Server Actions, and the properties of the attributes used.

Something very important to remember from this chapter is the fact that we should, whenever possible, abstract and isolate the manipulation of our data in Server Actions so that we can better control their integrity. In addition to being careful in Server Actions, we must always remember to set the Expose Read Only attribute of our entities to Yes. With this we guarantee that the data in our entities is only handled by our Server Actions in the consumer modules, thus guaranteeing that no user or application can write or change the data without complying with the defined rules, preventing the existence of dirty data.

As we have seen, we are...
