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.

Creating associations between entities to relate objects

In this section, you will start to explore associations between entities. Often there is a relationship between two different entities. Perhaps there are orders associated with inventory items or customers. Maybe you have multiple addresses or phone numbers associated with a single customer object. The way you look at the app's data model will help you understand how different entities are related.

Associations are used to represent the relationship between two entities. In Mendix Studio Pro, an association is drawn by clicking the edge of one entity and dragging a line to the edge of another entity or by editing the Associations tab of the Entity properties dialog window. Associations have a property known as multiplicity. This property describes the relationship between entities in terms of one-to-one, one-to-many, or many-to-many. Multiplicity is shown in Mendix with a one (1) or a star (*).
