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.

Chapter 6: Understanding Domain Model Basics

Welcome to the world of domain models! The Domain Model of the Mendix app represents the data layer of the application. When you are building an application, it is necessary to store the data for this application in some sort of structure. Mendix Studio Pro (and Studio) provides all the tools necessary to design the data structure of the app and display data in the app to your end users. Data could be things such as customer or order information and even an inventory of available videos to rent in the case of our fictional video store.

The domain model element of the module is where you visually design its data architecture. Modules can share data with each other in your Mendix app. The domain model consists of entities, which can be equated to tables in a relational database, and are also referred to as objects. These can also be referred to as transient objects in the case of entities that do not persist in the database. The domain...
