Applying the domain modeling approach

Applications that are database-focused or built from core functionalities without collaborating with models are either not easy to manage when they scale up or not friendly when enhanced or bug-fixed. The reason behind this is the absence of the structure and flow of business logic to follow, study, and analyze. Understanding the behavior of an application and deriving the domain models with the business logic behind them encompasses the best approach when it comes to establishing and organizing a structure in an application. This principle is called the domain modeling approach, which we will now apply to our ERP specimen.
