RDL Builder

Purpose-built for data modeling and schema governance, RDL Builder accepts entities, attributes, and relationship definitions to produce a verifiable data layout representation. It supports required vs optional fields, enumerations, defaults, and basic type mapping to reflect real-world constraints. Conceptually, the model is a network of entities connected by relationships, with validations that ensure referential integrity and consistent normalization hints. Advanced rules let users define derived fields and conditional constraints, while cross-entity checks catch inconsistencies before implementation. Outputs include JSON Schema-like definitions and an internal model graph suitable for downstream tooling or documentation. Use cases span API contract design, database schema planning, and data pipeline schema curation, enabling teams to align on structure early and reduce rework later. The tool emphasizes reproducibility, traceability, and collaboration across product, engineering, and data teams by exporting governance-ready artifacts and a readable model specification.
