Building Low-Code Applications with Mendix

By: Bryan Kenneweg, Imran Kasam, Micah McMullen

Overview of this book

Low-code is a visual approach to application development. It enables developers of varying experience levels to create web and mobile apps using drag-and-drop components and model-driven logic through a graphic user interface. Mendix is among the fastest-growing platforms that enable low-code enthusiasts to put their software ideas into practice without having to write much code, and Building Low-Code Applications with Mendix will help you get up and running with the process using examples and practice projects. The book starts with an introduction to Mendix, along with the reasons for using this platform and its tools for creating your first app. As you progress, you’ll explore Mendix Studio Pro, the visual environment that will help you learn Mendix app creation. Once you have your working app ready, you’ll understand how to enhance it with custom business logic and rules. Next, you’ll find out how to defend your app against bad data, troubleshoot and debug it, and finally, connect it with real-world business platforms. You’ll build practical skills as the book is filled with examples, real-world scenarios, and explanations of the tools needed to help you build low-code apps successfully. By the end of this book, you’ll have understood the concept of low-code development, learned how to use Mendix effectively, and developed a working app.

Understanding generalizations and specializations of entities

The concept of generalization and specialization (or inheritance as it is often referred to) can be a little tricky to wrap your head around if you don't already have experience with it. The basic concept is that generalization entities sit at the top of the hierarchy and specializations are customizations of the generalization entity. Figure 11.10 shows what this would look like in the domain model:

Figure 11.10 – Domain model with generalization and specialization entities

As shown in Figure 11.10, one example to help better explain this would be if you had a domain model with an entity called Vehicle. Vehicle contains attributes that would be common for any vehicle, such as Color, YearBuilt, and Weight. However, the application deals with very specific classes of vehicles: vehicles that travel on land and vehicles that travel through the air. In this case, you decide to create specialization...
