  1. Ubiquitous Language<\/strong><\/li>\n<\/ol>\n\n\n\n
      \n
    • Shared language between developers and domain experts<\/li>\n\n\n\n
    • Consistent terminology across code, documentation, and conversations<\/li>\n<\/ul>\n\n\n\n
        \n
      1. Bounded Contexts<\/strong><\/li>\n<\/ol>\n\n\n\n
          \n
        • Clear boundaries that define where models apply<\/li>\n\n\n\n
        • Each context has its own ubiquitous language and model<\/li>\n<\/ul>\n\n\n\n
            \n
          1. Context Mapping<\/strong><\/li>\n<\/ol>\n\n\n\n
              \n
            • Explicit relationships between bounded contexts<\/li>\n\n\n\n
            • Strategies for integration across context boundaries<\/li>\n<\/ul>\n\n\n\n

              1. Strategic Design<\/strong><\/li>\n<\/ol>\n\n\n\n
                  \n
                • Core Domain – Most valuable and complex part of the system<\/li>\n\n\n\n
                • Supporting Domains – Essential but not differentiating<\/li>\n\n\n\n
                • Generic Domains – Can be outsourced or use off-the-shelf solutions<\/li>\n<\/ul>\n\n\n\n
                    \n
                  1. Tactical Design Patterns<\/strong><\/li>\n<\/ol>\n\n\n\n
                      \n
                    • Entities<\/strong> – Objects with identity and lifecycle<\/li>\n\n\n\n
                    • Value Objects<\/strong> – Immutable objects defined by attributes<\/li>\n\n\n\n
                    • Aggregates<\/strong> – Cluster of entities and value objects with a root entity<\/li>\n\n\n\n
                    • Domain Events<\/strong> – Objects that capture occurrences in the domain<\/li>\n\n\n\n
                    • Repositories<\/strong> – Provide collection-like interfaces for accessing domain objects<\/li>\n\n\n\n
                    • Factories<\/strong> – Encapsulate complex object creation<\/li>\n\n\n\n
                    • Services<\/strong> – Operations that don’t belong to entities or value objects<\/li>\n<\/ul>\n\n\n\n

                      1. Domain Model<\/strong><\/li>\n<\/ol>\n\n\n\n
                          \n
                        • Rich, behavior-focused model of the domain<\/li>\n\n\n\n
                        • Encapsulates business rules and processes<\/li>\n<\/ul>\n\n\n\n

                          1. Anti-corruption Layer<\/strong><\/li>\n<\/ol>\n\n\n\n
                              \n
                            • Isolates models from external systems<\/li>\n\n\n\n
                            • Translates between different contexts<\/li>\n<\/ul>\n\n\n\n
                                \n
                              1. Continuous Integration<\/strong><\/li>\n<\/ol>\n\n\n\n

                                • Frequent merging of models to maintain consistency<\/li>\n\n\n\n
                                • Regular validation of the model against domain requirements<\/li>\n<\/ul>\n\n\n\n

                                    • Implementation closely reflects the domain model<\/li>\n\n\n\n
