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.

Distributing modules across applications

Modules must be organized within applications according to the layer to which they correspond. For this, we will be based on OutSystems Architecture Canvas, also called 3LC or 3 Layer Canvas.

Tip

The OutSystems architecture model from now on will simply be called 3LC.

This model is applied on two levels: the applications level and the modules level. What does this mean? Both applications and modules correspond to certain layers, and applications adopt the topmost layer of the module that constitutes it, which has the upper layer. For example, an application that contains a foundation layer module and a core layer module is from the core layer, since the top module that composes it belongs to this layer. If this application contains an end user layer module, it will assume the end user layer.

The typical OutSystems framework architecture layers and their properties are as shown in Figure 4.3:
