              SchemaDraw translates configurations directly into standard **PostgreSQL DDL commands**. The generated schema objects are compatible with most Postgres-compatible engines, including Supabase, Neon, and AWS Aurora.
            

          

        


        
        

          
          

            

              Each column has an anchor point. Toggle the **PK** selector to identify primary keys, and use the **FK** selector dropdown on a foreign column to map the relationship. SchemaDraw draws SVG bezier paths connecting the endpoints.
            

          

        


        
        

          
          

            

              Currently, SchemaDraw targets the PostgreSQL client dialect. We are adding support for MySQL and SQLite translations in the upcoming visual release.
            

          

        


        
        

          
          

            

              No. SchemaDraw's validation pipeline automatically screens relationships for circular dependencies and key mismatches. This helps you avoid database constraint conflicts when deploying DDL statements.
