What ER/Studio Data Architect is
ER/Studio Data Architect is a paid, self-hosted Windows solution for individuals and small teams creating, documenting, and optimizing data structures. It supports logical and physical data modeling, can generate a database from a model, and can extract a model from an existing database. Schema Compare & Merge detects differences between database versions and produces ALTER scripts. A local data dictionary standardizes names, metadata, and business rules, while macros automate repetitive work. Named database platforms include SQL Server, Oracle, PostgreSQL, Databricks, Snowflake, and MongoDB. JSON schemas can be imported, exported, and modeled. The maker offers a 14-day trial without a credit card. Data Architect excludes repository support, version control, model sharing, and governance integrations. It includes some MetaWizard bridges; the full bridge list is in Enterprise Team Edition. The maker identifies architects, administrators, freelancers, consultants, startups, and small businesses as users.
