You should seriously consider installing the Oracle DBMS on your personal machine. As of Spring 2005, you could get a free (for educational purposes) license from Oracle for version 10g.

• Log in to the NCSU Oracle DBMS as described here
• Where it asks for user-name, type in your-unity-ID@orcl.world (e.g., mpsingh@orcl.world)
• Where it asks for password, type in your student ID (the default initial password). There are instructions here for changing your password.
• It is simplest to edit an SQL script with a text editor and load it in via start, e.g., as in
  

  start foo.sql

• Sometimes it helps to log your session, which you can do via spool as in
  

  spool filename.log

• The SQLPlus help command can be useful. Invoke it as in
  

  help create table

• To view all tables and views, enter
  

  select * from system.tab
