Oracle SQL Developer is a free, graphical tool that makes it easy to work with Oracle databases. So easy, in fact, that author Joel Murach thinks you should use it right from the start. So this free chapter from his new book, Murach's Oracle SQL and PL/SQL, shows you how to use SQL Developer to work with database objects and to build and run SQL statements. http://www.murach.com/books/osql/chapters.htm
