Erwin Data Modeler is a professional data modeling and schema design tool used to create, visualize, and maintain conceptual, logical, and physical data models. It supports forward and reverse engineering, automated DDL generation, and compare-and-merge capabilities to synchronize models with live databases. The platform works with major relational and cloud data warehouse systems, including Oracle, Microsoft SQL Server, PostgreSQL, MySQL, IBM Db2, Teradata, and Snowflake.
Built-in standards for notations (such as crow’s foot/IE), naming conventions, datatypes, and domains help enforce consistency and improve data quality. Collaboration features—such as a shared repository, version control, and reusable design assets—enable teams to coordinate changes, perform impact analysis, trace lineage, and produce documentation for governance and compliance. Common use cases include designing new application schemas, modernizing legacy systems, supporting cloud migrations, and aligning analytical models with operational data sources.
