What if there is no Oracle installed in your system

You want to test a SQL query. But you don't have a oracle client or server available at your place - no oracle products are installed at your place.

If you are blessed to have an internet connection, you are empowered, can test all your SQL queries.

Oracle has provided a web based environment, all what need to do is, very first time use the URL to create an account with minimal details and accept the conformation sent to your mail id, log in with your credentials that you supply during creation of an account (password will be sent to your mail id and first time log in will ask you to change the password) and work. Thats all about it.

The advantage is, you only create account once and can use that any time, no need of creation of account all the time. You will have separate database that is used only by you. Everything is independent.

So, when ever you want to test something go to the URL, log in and test

Have the account created now, you never know, you may require to test something remotely.
