Define Once, Enforce Everywhere: Model-Driven Design Using Legend - Sumit Rastogi Deepika Srivastava

This session explores the challenges enterprises face in managing data consistently across multiple systems, which can result in configuration drift and increased regulatory risk. The speaker presents a model-driven data architecture that promotes the business domain model as a system-agnostic, executable specification using Legend, an open-source platform. This approach integrates a logical modeling language and declarative annotations that allow teams to embed governance, security, and behavioral policies directly into the model at design time. The session also highlights how the compilation of these enriched models into platform-specific artifacts helps eliminate configuration drift and fosters trustworthy automation by generating accurate machine-readable semantics from a single model.
