Learning Dynamics NAV Patterns

By: Mark Brummel, Marije Brummel

Overview of this book

Microsoft Dynamics NAV is a complete ERP system, which also contains a robust set of development tools to support customization and enhancement. These include an object designer for each of the seven application object types, a business application-oriented programming language with .NET interface capability, a compiler, a debugger, and programming testing language support. Learning Dynamics NAV Patterns will guide you through the NAV way of solving problems. This book will first introduce you to patterns and the software architecture of the NAV and then help you to build an example application. Then, it walks you through the details of architectural patterns, design patterns, and implementation patterns. This book will also talk about anti-patterns and handling legacy code. Finally, it teaches you to build solutions using patterns. Proven patterns and best practices will help you create better solutions that are easy to maintain in larger teams across several locations. It will guide you through combining abstract patterns using easy-to-understand examples and will help you decide which patterns to use in which scenarios.

Class-Method-Property

The Microsoft Dynamics NAV Development Environment allows us to write code in almost any place within the application. Each object has dozens of triggers that allow writing C/AL code.

If we just write bits and pieces of code everywhere in the objects, the maintainability of the application would be hard for anyone, including the original developer.

To write code in such a way that other developers can find their way requires a set of rules. If we apply these rules, it will be easier for others to see what we did, because we will reduce the number of places where we write business logic.

The Table as a class

Before we start coding, we need to find the owner of a process. If we explicitly connect the process to the owner, it will be easier for everyone who works with the object to understand what it can do.

Let's try to clarify this with an example. One of the processes that has a lot of owners in Microsoft Dynamics NAV is printing an address...
