The document discusses strategies for organizing complex domain models across teams and applications. It introduces the concept of bounded contexts to define the scope of individual domain models and establish consistency boundaries. Context maps are proposed to visualize the relationships between bounded contexts and identify points of integration. The document also discusses data ownership considerations, noting the tradeoffs between data duplication and integrity. Integrations strategies like shared kernels and anticorruption layers are presented to enable communication between bounded contexts while maintaining independence.
An Introduction to Domain Driven Design focusing on the concepts of Bounded Context, Strategic & Tactical Design, CQRS, Ubiquitous Language, Hexagonal Architecture, Event Sourcing, Task - based UIs
You’re invited to join us for a mini-workshop on Integrating Bounded Contexts with RabbitMQ. We’ll cover the concepts you need to know and we’ll put them to practice in a sandboxed environment (a very simple example PHP project). Some of the topics that will be discussed:
Bounded contexts, domain events, commands, enterprise integration patterns, (de)serialization, (de)coupling, messaging, RabbitMQ.
Bounded Context e CQRS na evolução de aplicações .NET legadasYan Justino
Nesta palestra vamos explorar como design e técnicas modernas da engenharia de software, especialmente Bounded Context e CQRS, podem ser usadas com sucesso na manutenção evolutiva de sistemas legados.
Com base em experiências reais, veremos como aplicar esses conceitos em sistemas críticos, preparando-os para uma distribuição mais segura e eficiente. Também será apresentado como elevar as técnicas para um novo patamar de qualidade, de forma alinhada ao interesses da organização.
Apresentaremos as estratégias usadas para evolução de aplicações .NET legadas de sistemas públicos de grande porte, e veremos como um sistema, antes pouco escalável e de alto custo, vem sendo portado para um cenário passível de testes e com grande escalabilidade e capacidade de distribuição.

For a few decades, one of the most common approaches to software design is to first focus on the domain model (application layer), then persistence (data layer) and finally the user interface (presentation layer). But what are the pros and cons of this approach? Are there other alternatives? Are they viable? In this presentation, Sandro will be talking about different design biases and the impact they have. He will then focus on Outside-In Design, explaining how our domain model can emerge and evolve when driven by the needs of external systems or users, avoiding speculation and wasted effort.

Regardless of the content architecture (DITA, DocBook, Structured, Un-Structured, etc…) you should have a strategy around your content creation and production. But is your strategy working for you? Is it delivering what your customers are looking for? Can they find what they need? Do they actually enjoy using your content?
Looks at developing a product content strategy that comes from the outside (your customers side): A strategy that will not only keep your content consumers satisfied, but that will keep you modern and current even as technologies and consumers change over time.
The first day slides of the Domain Driven Design course that I imparted on Schibsted Spain.
They talk about technical debt, domain modeling, model driven design and SOLID principles.
Domain driven design is help as part of software development for proper deliver of software applications.
It will help on strategic planning of software design and delivery.
Aligning Bounded Contexts with Subdomains in Legacy Code - NDC Oslo 2021Mufrid Krilic
One way or another, each system contains some kind of boundaries. I would go so far and claim that even the dreaded Big Ball of Mud systems consist of parts that could be perceived as separate though undoubtedly only under deep scrutiny. The difference is in the “thickness” of the boundaries and the measure of interrelationships between the different parts of the system, the frequency and amount of data that is passed across the fences. It is the latter that leads to increased coupling resulting in systems that are hard to maintain and hard to change.
This presentation will present a story of an attempt to achieve an alignment between perceived subdomains, logical boundaries and source code structure in a legacy system. Based on the use case from healthcare we will go into technical detail on concrete steps that were followed to create a new bounded context using strategic Domain-Driven Design and 4+1 Architectural View Models.

It is quite possible to use Agile techniques for creating and maintaining a data architecture. Doing so will dramatically reduce the risk of failed data warehouse projects. This webinar will give you a quick overview of the benefits and challenges of Agile Data Modeling, Evolutionary Database Design, Agile Modeling, Conformed Dimensions, Bus Matrix, Database Refactoring, and an Agile framework for Agile data projects
The first session on design patterns that makes the audience aware of the patterns.
P.S. The implementation are more from explanation perse rather than focusing on being 100% correct. The idea is to make the audience understand patterns rather than putting 100% correct code for the pattern.
3. Strategic Design
Why?
• Scaling up complex domain models
• Total unification of the domain model for a large system
will not be feasible or cost-effective
• Modularity without losing benefits of integration
5. Strategic Design
What?
• Need for a systematic, evolving design strategy
• Doesn’t happen by itself or through good intentions
• Proactive decisions about what should be unified
• Pragmatic recognition of what’s not unified
6. Bounded Context
• Defines the range of applicability of each domain model
• Multiple models coexist and apply in different contexts
• Defines consistency boundaries
8. Bounded Context Not Defined
• Unclear in what context model should be applied
• Unclear in what context model should not be applied
• Lack of focus and confusion by issues outside
9. Bounded Context
How?
• Explicitly define a scope of a particular model
• Explicitly set boundaries
• Team organization
• Usage within a specific application
• Physical manifestation (codebase and DB schema)
10. Bounded Context
Clarity & Freedom
• Keep the model consistent within its bounds
• Team responsible for the model deals with the whole
lifecycle of each object, including persistence
• Teams don’t get distracted or confused by issues outside
13. Context Map
• Identify each Model on the project
• Define Bounded Context
• Name each Bounded Context
• Describe points of contact between models
• Outline explicit translation
• Highlight any sharing
18. Context Map
• Bounded Contexts partition should be based on cost-
benefit trade-off:
• Independent team action
• Direct and rich integration
19. Larger Bounded Context
• Flow between user tasks is smoother (unified model)
• Coherent and easy-to-understand model instead of two
distinct ones plus mapping
• Translation between two models can be difficult
• Shared language fosters clear team communication
20. Smaller Bounded Context
• Communication overhead between developers is
reduced
• Continuous integration is easier with smaller teams and
code bases
• Different models can cater to special needs
• Ubiquitous language dialects can be encompassed by
smaller models
22. Integration Strategies and Recipes
• Shared Kernel
• Customer/Supplier
• Conformist
• Open Host
• Published Language
• Anticorruption Layer
• Separate Ways
28. Data Duplication
The data may be stale…
but is that really an issue?
29. Data Integrity
• Different data has different requirements
• Product Specifications
• Product Assets
• Product Pricing
• Product Recommendations
• Cost-benefit analysis
Editor's Notes
Monolithic all-encompassing domain model on one side of the spectrum (duplications, contradictions)Set of small, distinct sub-systems glued together with ad-hoc interfaces (lacks the power to solve enterprise-wide problems)
Metaphor:Cells can exist because their membranes define what is in and determine what can pass!
Don’t get distracted or confused by issues outside
BOUNDED CONTEXTS gives team members a clear and shared understanding of what has to be consistent and what can develop independently.
Litmus Paper Duplicate concepts: two model elements that represent the same conceptFalse cognates: two people who use the same term and think they are talking about the same thing, but they are not (less common, more insidiously harmful)
People on other teams won’t be aware of the CONTEXT bounds and will unknowingly make changes that blur the edges or complicate interconnections.
Overlap between project management and software design
MAP THE TERRAIN
SUBSTANCE OVER FORMWhatever forms the MAP takes it must be shared and understood by everyone on the projectMust provide clear name of each BC and must make points of contact and their nature clear
“We spend a great deal of effort maintaining data, maintaining integrity, maintainingconsistency, and some fool wants to duplicate this problem all over, now we have two lots of datato manage and synchronise!”The only issue that really exists is that this data could be stale or inconsistent – it may be 5seconds out of date, or 10 seconds, or maybe just 1 second – but this data may not be up to date.Well, of course it may not be up to date… but is any of the data in your system really up to date?Even if you just requested it from your Domain, and it appeared on screen, before you hit anykey on your keyboard, that data is already stale – by the time you press “update” someone orsomething else may have modified the data.Eventually the data may be up to date and consistent, it just may not be the instant you request it.So yes, the data may be stale, but is that really an issue? (hint: the answer is no)
