Two contexts share a subset of the domain model and database.
When Eric Evans published his work, the software industry was heavily focused on technology-centric architectures. Developers often designed systems around database schemas, frameworks, or specific coding patterns rather than the actual business problems they were trying to solve.
Eric Evans structured his book into 4 parts spanning exactly 18 chapters. Together, they form a progressive roadmap. They take readers from basic conversations with business experts to complex architectural patterns for massive corporate systems.

External objects are only allowed to hold references to the Aggregate Root, never to the internal components. This guarantees that all business invariants (rules) are strictly enforced. Repositories and Factories

To help you get the most out of your study of Domain-Driven Design, let me know: Two contexts share a subset of the domain model and database
Strategic design addresses the high-level architecture and organizational boundaries of a software system.
The downstream team simply conforms to whatever the upstream team provides.
Strategic design prevents large systems from collapsing into a "Big Ball of Mud." It focuses on mapping out relationships between different parts of an organization. Eric Evans structured his book into 4 parts
The Blue Book was written in 2003, but the truth of Chapter 18 will outlive Python, Rust, and AI coding assistants. Domain complexity is forever. Get the real EPUB, turn to page 347 (Chapter 18), and save your next project.
: The model develops in tandem with the developer's understanding of the business domain and the expert's understanding of how the model solves their problems.
