Why the Anemic Domain Model Is a Hidden Anti‑Pattern and How Rich Models Save You

This article examines the anemic (transaction‑script) versus rich (active) domain model patterns, explaining their origins, drawbacks, and benefits, and shows why embedding behavior in domain objects aligns with true object‑oriented design while over‑reliance on service layers leads to costly anti‑patterns.

Why We Shifted Away from Database‑Generated IDs to 64‑Bit Domain IDs

The article explains how our team, while building a SQL Server data catalog, adopted decoupling principles to avoid coupling business logic to a specific database, opting for domain‑generated 64‑bit IDs instead of database‑generated keys, and discusses the benefits of Snowflake‑style ID generators.
