In Oracle there are two major interfaces. For a beginner asking the questions you are asking I would suggest DBCONSOLE, also known as OEM or Oracle Enterprise Manager: The other is SQL*Plus.
Good places to start your exploration of Oracle are at:
http://tahiti.oracle.com http://docs.oracle.com http://asktom.oracle.com http://www.psoug.org/library.html
And the best general advice I can give you ... Oracle is nothing like SQL Server. Don't do anything until you read the concepts and [Quoted] architecture books. Trying to make Oracle work like, or behave like, a Microsoft product is as productive as trying to teach a pig to sing.
