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.

The 3 Layer Canvas (Architecture Canvas)

The Architecture Canvas is the tool that allows us to streamline and easily create a scalable, robust, and well-performing architecture.

This model is prepared and designed for the most critical scenarios with multiple applications and modules existing in an OutSystems factory.

The Architecture Canvas has layers and sub-layers in its base into which the application context is divided. Each layer and its respective sub-layers will contain applications and modules with different characteristics and types of functionality.

As such, the layers are organized as shown in Figure 13.1:

In addition, and in order to make the interpretation and segmentation of the code simpler and more correct, the same layers are divided into sub-layers, allowing a quicker inference of the nature of each module and application. The layers are organized as shown in Figure...
