Discover some of the core concepts of 4D: tables, fields, data types, project forms, and methods

Learn how to build a simple, fast, and ergonomic interface, using the most current methods of coding with 4D, using ORDA and objects, in Project Mode.

In this training session with Reda Mourad, you will learn, step by step, how to build a 4D application from scratch using the newest methods of coding with 4D.

During this journey through the 4D platform, you will develop a complete project management application.

The training will highlight the simplicity of the interface, and how to navigate it for the best possible user experience, delivering successful applications while making customers and users happy.

Listen to the key benefits in this introduction video.

Who should attend this session?

• Professional developers new to 4D, joining teams developing and maintaining business applications in 4D using ORDA, the latest technologies in Project Mode, and following the most up-to-date optimal practices.

• Experienced 4D professional developers or Project Managers, willing to learn new up-to-date tools to code with 4D using ORDA, the object revolution, as well as conversion to Project Mode, to benefit from all the new features and possibilities offered by the latest 4D versions.

Note: If you’re a professional developer looking at starting with 4D, joining a team developing and maintaining an existing business using classic language and concepts, please consider the 4D for beginner training, already available OnDemand on the 4D Store.
