DBeaver
Free universal database tool
DBeaver is a free, multi-platform database tool that supports any database having a JDBC driver. It is useful for developers, SQL programmers, database administrators and analysts.
DBeaver comes with plenty of great features such as metadata and SQL editors, ERD, data export/import/migration and more. Plugins are available for certain databases, and there are also several database management utilities. DBeaver’s Enterprise Edition provides even more features and supports non-JDBC datasources.
