Overview

“Introduction to Domain Models” is a foundational course designed to help learners understand the concept and practical application of domain modeling in software and systems design. Aimed at developers, business analysts, software architects, and technical project managers, the course explores how domain models serve as a bridge between real-world business problems and their software solutions. Participants are introduced to the key principles of domain-driven design (DDD), including entities, value objects, aggregates, and bounded contexts. Through clear examples and practical scenarios,...

Constructing Domain Models

In this module we will explore the concept of domain modeling by revisiting the university model we touched on in earlier modules. In this module, we will review a comprehensive depiction of how a university system operates, encompassing crucial elements like courses, schedules, student experience, and the connection between student needs and university offerings. As software engineers, understanding domain modeling becomes essential, as it serves as the foundation for building effective registration systems and provides a graphical description of the physical situation that guides the design of the underlying application, mapping directly to software code.

Domain Model Implementation

In module 2, we will examine the university case and the actual process of transforming the design into code and making effective decisions along the way. We have already addressed the hierarchical structure and broken down components into simple and deliberate entities. Now, the focus shifts to writing code strategically, starting with the class or component with the least dependency. Throughout this module we will explore decision-making in code implementation to create real value from designs.

The Xerox Case - Part 1

This module we will pivot to explore a different framework through another case study: this time we will be focusing on Xerox.We will learn about the challenges that faced Xerox and consider possible design solutions that will Xeroxs problems. As we get into the material in this case, it is important to remember that paying close attention from the very beginning is essential to driving transformation and solving complex problems.

The Xerox Case - Part 2

This module we will continue our exploration of the Xerox Range Pricing Model. Last module we explored user tasks for the Xerox sales team. Now, we will dive more into transforming the process used by Xerox into an actual, working software design system.
