Oracle SQL Developer is a free graphic tool that Oracle provides for developing, or simply to execute SQL queries or scripts, DML or DDL, on Oracle databases.

The appearance and funcionality is similar to that offered by commercial tools like TOAD or PL/SQL Developer, but it's not the same. Oracle SQL Developer is more simple, but we have to bear in mind that it is a free tool.

A useful feature incorporated in last releases is the possibility of connecting with another databases like SQLServer, MySQL or Access. It is easy to configurate it to connect with MySQL and SQLServer using a JDBC driver. Once the connection is established, you can explore objects of this databases the same as if it was an Oracle database.
