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.

Analyzing data synchronization patterns

One of the capabilities that allow mobile applications to be quite functional is the fact that they allow data synchronization between the database and Local Storage These scenarios are very useful in contexts where applications work offline and data needs to be synchronized on both sides.

For this, OutSystems designed five synchronization patterns:

  • Read-Only data – This pattern is useful for applications that only need to read data offline and the volume of data to transact between the database and Local Storage is low. This pattern is based on the principle of deleting all existing data on the Local Storage side, retrieving the data from the database, and creating it again on the Local Storage. An action for synchronizing Local Storage entities generated from database entities can be created automatically:
