Everything you need for professional database modeling
Intuitive drag-and-drop interface for creating tables, relationships, and complex database structures.
Support for Relational (SQL) and Analytical databases (Data Warehouses). NoSQL support coming soon!
Export your models to XMI, SQL DDL, OWL/Protégé, JSON, and Data Dictionary formats.
Document business rules, constraints, and field descriptions directly in your model.
Automatically organize your models with hierarchical, force-directed, and circular layouts.
Create reusable and shareable domains across your models. Define common entities like Customer, Product, Order, and Order Item once, then reuse them across multiple projects.
Track changes, create versions, and restore previous states of your database models.
Import entities directly into your model from SQL, XMI, and JSON files. Jumpstart your design by reusing existing schemas and structures without manual re-entry.
Define and enforce naming conventions across your entire model. Keep entities, attributes, and relationships consistent with your organization's standards automatically.
Automatically analyse your model and get a quality score with actionable insights. Detect missing descriptions, inconsistent naming, undocumented fields, and other issues before they become problems.
Compare any saved version against the current model. Instantly see which entities, attributes, relationships, and indexes were added, removed, or modified.
