Aqua Data Studio is a multi-database IDE that talks to SQL Server, Oracle, PostgreSQL, MySQL, DB2 and Snowflake through the same query editor, schema browser and result grid.
Beyond querying it ships visual analytics for charting result sets, an ER modeler for designing schemas, a visual Explain Plan viewer and script management that plays nicely with version control. The same client is used for profiling and comparison work during migrations.
