Guide: Domain Object Modeling in PMI-ACP / FDD

Domain Object Modeling is an important process used in Feature Driven Development (FDD) for the structure of a system using a collection of conceptual objects and services.

Why it is important: It provides a structured model that represents a system and its characteristics. This makes it easier to understand the system and its functionality; hence increasing the effectiveness of software development. It also promotes code reuse and facilitates team communication.

What it is: Domain Object Modeling is a practice in which developers create a model of the system using objects. This model includes objects that represent the entities in the business domain, their attributes, behaviors, relationships, and responsibilities.

How it works: In Domain Object Modeling, an object model is created to represent the system. This model is a pictorial representation of the structure and behavior of the system's objects. Developers detail the properties and operations of each object, as well as their interactions. The model aids in defining the business logic and analyzing how the system behaves.

Exam Tips: Answering Questions on Domain Object Modeling Understanding the concept of Domain Object Modeling is key to answering related questions effectively. Be sure to understand the characteristics of the Domain Object Model such as objects, properties, operations, and the interactions between these objects. Practice creating object models and ensure you clearly understand how to use them for different system scenarios.

Your approach should be to identify the major entities in the given scenario, model them as objects, and demonstrate their interactions. Know that every object has a state, behavior, identity; and objects communicate by sending and receiving messages.

Domain Object Modeling practice test

Domain Object Modeling is a vital aspect of Feature Driven Development. In its essence, it represents an extensive and visual interpretation of the parts involved in building a system. This model is developed by a chief programmer, a domain expert, and other members who have deep insight into the problem domain. It requires understanding of the system, discussing models and relationships between them, and defining the overall model structure. The result teases out the features in terms that are meaningful to the business. This provides a solid foundation for other phases of the FDD process.
