Machine Learning Engineer
In this training , you training why Domain Driven Design (DDD) can make complex software projects more transparent for everyone involved. At the same time, you will learn a range of practical techniques and elements that can be used to achieve an optimized domain model.
The core content includes event storming to familiarize yourself with the domain, strategic thinking to divide the domain, and cutting and distinguishing models from one another. Other topics include ubiquitous language, domain logic patterns, and tactical design. In addition, there are advanced topics such as local model consistency, implementation of building blocks, design by contract, CQRS and event sourcing, and microservices.
Domain, model, and ubiquitous language:
- Structured acquisition of domain knowledge and representation in a model
- Establish a uniform technical language for developers and subject matter experts
Domain, model, and ubiquitous language:
The path to the model
- Use modeling techniques such as event storming or domain storytelling
- Extract knowledge from domain experts and refine it iteratively
From model to implementation:
- Connect domain model with technical building blocks such as aggregates, repositories, and services
- Understanding the impact of model changes on implementation
The model in the application architecture:
- Integration into architectural concepts such as hexagonal architecture or layered architecture
- Clarify the connection between domain-driven design and behavior-driven development
Cut out the model and separate the parts:
- Define bounded contexts and create clear interfaces between models
- Identify subdomains and strategically divide them into core, supporting, and generic subdomains.
Maintain local model consistency:
- Use anti-corruption layers to isolate external dependencies
- Using domain events as an asynchronous means of communication between bounded contexts
Requirements:
- You should have a good grasp of the fundamentals and advanced concepts of object-oriented software development.
- Experience in modeling object-oriented architectures is required.
- Knowledge of agile methods such as Scrum, Kanban, or XP is helpful.
- You should already software developers experience working with specialist departments and software developers
- A basic understanding of domain models and their practical application will make it easier for you to get started.
Technical requirements:
There are no special requirements for the training environment, as the exercises take place using cloud- and web-based tools such as Miro, Draw.io, and platforms such as Jupyter or HuggingFace. All that is needed is a stable and sufficiently fast internet connection.
- You will learn to develop complex domain models that accurately represent the subject domain.
- You will acquire skills for establishing a uniform language between technical andexperts.
- You can design models iteratively and agilely and organize collaboration with domain experts effectively.
- You understand how domain models are integrated into software architectures and can be strategically tailored.
- You will deepen your knowledge of techniques such as event storming, context mapping, and modularization.
- You are able to master the challenges of large, distributed systems and create sustainable software solutions.
Your advantages at a glance:
- Clear technical language & better communication: A standardized ubiquitous language facilitates collaboration between developers subject matter experts.
- Structured modeling & scalability: Bounded contexts and strategic model partitioning keep the software manageable even as complexity increases.
- Flexibility & adaptability: Domain models can be developed iteratively to adapt to new requirements.
- Visual collaboration through, for example, whiteboarding
- High level of interactivity through customized exercises and breakout rooms
- Ideal trainer support even in the breakout rooms
Credit points for CPSA-A certification:
