In this session you will see how ORDA and objects are used in real life in production. You will learn how to handle null and undefined values and all what you need to know to program clean, safer and faster code. This session gives you new concepts and approaches into your hands and will open you new possibilities and advantages compared to the classic 4D language. You will learn how to handle locking, create own classes, using formulas, doing fast queries with related entity-selections and a bunch of dos and don’ts.
