The SQuirreL SQL Client is a database administration tool that allows you to view the structure of a JDBC compliant database, browse the data in tables, issue SQL commands etc. It uses JDBC to allow users to explore and interact with databases via a JDBC driver.
The software provides an editor that offers code completion and syntax highlighting for standard SQL.
It also provides a plugin architecture that allows plugin writers to modify much of the application’s behavior to provide database-specific functionality or features that are database-independent.
