Oracle SQL Developer was developed in Java leveraging the Oracle JDeveloper IDE framework. Default connectivity to the database is through the JDBC Thin driver (no Oracle Home required); the JDBC Type 2 driver (OCI client side driver) is also supported. There is a separate release available bundled with JRE 1.5, with an additional tools.jar to support Windows clients. Non-Windows clients only need JDK 1.5. or later. Installation is performed simply by unzipping the downloaded file.
