ERBuilder

ERBuilder is a desktop data modeling tool from Softbuilder for designing, documenting and generating relational database schemas. Modelers lay out tables, columns, keys, indexes, domains, views, stored procedures and triggers on a diagram, then forward engineer the result into a live database or reverse engineer an existing one into a model. Supported platforms include Oracle, Microsoft SQL Server, MySQL, MariaDB, PostgreSQL, SQLite, Firebird, Azure SQL Database, Azure Synapse Dedicated SQL Pool, Amazon Redshift and Amazon RDS. It is aimed at data architects, data modelers, analysts and developers who maintain schemas across more than one database engine. Capabilities that matter include model validation, generation of SQL and DDL scripts, support for before and after scripts at project and table level, version management, navigable HTML documentation plus Microsoft Word output and publishing straight into Confluence, test data generation, and a database sandbox for validating a model against real data. Generative AI features produce entity relationship diagrams automatically from a plain language description of the data model. The product ships in Free, Professional and Enterprise editions, and the feature matrix sets out exactly what each one includes. Pricing is published in three forms. Subscription licenses cover one workstation for one year with support and updates, at $139 per year for Professional and $399 per year for Enterprise. Perpetual workstation licenses cost $279 for Professional and $799 for Enterprise, each with one year of support and maintenance, renewing at $99 and $199. Floating perpetual licenses for concurrent users cost $399 for Professional and $999 for Enterprise with a minimum order of two, renewing at $142 and $375. A free trial is offered on every tier.
