Business value
By supporting existing tables when you visualize a complex data model, the entity relationship diagram (ERD) data experience helps makers build meaningful business solutions on top of their existing data assets. With Copilot assistance, makers can easily find existing tables that fit their data modeling needs and build more robust business applications. With the ERD visualization of tables and relationships, makers can review new and existing tables side-by-side and define meaningful connections between them with a simple drag-and-drop interaction.
Feature details
Are you tired of creating new tables that duplicate existing tables in your environment? Use the Copilot-assisted ERD designer to design data models. Instead of starting from scratch, use your existing tables to build data models. Here's how it works: Enter your requirements in natural language. Copilot creates a multi-table data model that includes new and existing tables. Need to find relevant tables quickly? Copilot recommendations locate the right tables in seconds. After you assemble your tables, switch to the ERD view. You can review your new and existing tables. While editing existing tables in the ERD view isn't supported yet, you can create lookups into the existing tables with a simple drag-and-drop action to define connections between tables.
