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.

Chapter 6: Server-Side Logic

Our applications don't live only on data and beautiful screens. For all this to work, there has to be the glue that connects all the parts: logic! For this, at the backend level, the platform provides abstraction artifacts known as Server Actions that allow us to create functionalities and business logic. Through them, we are able to ensure the robustness of our data, efficiently follow business rules, and abstract complexity from our application.

This chapter focuses on developing our Server Actions in order to build and abstract our business rules and data handling in a robust and non-compromising way, thus facilitating the logical operation of our applications.

In this chapter we will cover the following topics:

  • Introducing logic actions
  • Types of variables in Server Actions
  • Taking logic decisions with conditional paths
  • Creating loops
  • Exercise 2 – Creating Server Actions
