Yantra Studio
Semantic ERD Modelling

ERDs that mean something.

Entities and attributes in Yantra Studio are structured objects — not boxes with text. Add datatypes, nullability, primary keys, foreign keys and domain constraints directly on the canvas. Your diagram and your data model are the same thing.

How It Works

From canvas to data model in one step

Step by step — exactly what happens under the hood.

01
Add an entity

Drop an entity shape on the canvas. Give it a name and start adding attributes — each with a name, datatype, nullability and key designation.

02
Define relationships

Draw a connector between entities to create a relationship. Set cardinality (one-to-many, many-to-many), define the join columns and add a constraint name.

03
Add domain constraints

Define check constraints, default values and unique constraints directly on attributes — all stored as structured metadata, not free text.

04
Export to DDL

Generate CREATE TABLE statements from your model at any time. The DDL reflects exactly what is on the canvas — no manual translation required.

05
Export to data dictionary

Export your full model as an Excel data dictionary with one click — ready for review or handoff.

Why It Matters

Built for real workflows

Not just a feature — a step change in how your team designs, reviews and governs architecture.

Benefit 01
Diagram and model as one object

The biggest problem in data modelling is keeping the diagram and the DDL in sync. Yantra Studio eliminates the problem entirely.

Benefit 02
DDL export on demand

Generate SQL CREATE TABLE statements directly from your model. No separate modelling tool. No manual translation.

Benefit 03
Review-ready

Every entity, attribute and constraint is structured data — which means it can be compared, versioned and audited. Not just viewed.
