Object-Oriented vs. Object-Based

C/SIDE is not object-oriented but object-based. This is an important distinction. In an object-oriented language or environment, a developer can create new types of objects based on the ones already in the system. In Microsoft Dynamics NAV, you can only create objects that are either tables, forms, pages, reports, dataports, XMLports, codeunits, or menu suite objects.Because there are a limited number of application objects, C/SIDE works faster and more efficiently. The greatest benefit is the Stability.
