Hi,

I am new to Oracle but did take a course in college. Anyway have been working in SQL Server and in there we would have to first create a Database, and then tables for it.
However, in looking around I do not see this for PLSQL in oracle. Do they have databases or is it something else?

Thank you

You first have to install Oracle software.
Then create a database (which is not the same thing than a database in SQL Server) and an instance on it.
Then connect to the instance using SYSTEM account and create a user which is also a schema granting it the appropriate privileges.
Then connect to this new user/schema and create the tables.

The first 2 steps can be done using Oracle installer from the files you downloaded.
Read the Oracle® Database 2 Day DBA book.

and the first thing to learn is that every database product is implemented entirely differently from all others. In this specific question, the entire concept of "database" is different. It should also be noted that because of different internals, what is considered 'best practice' in one rdbms product is actually 'worst practice' in another. I'd suggest you begin with the Database Concepts manual.

In fact, the very fact that Oracle publishes the Concepts is something that seems a strange concept in the MSSQL world. When I took a bunch of oracle DBA courses (administered by Oracle) the emphasis was on architecture and database internals/implementation. Same when I took a course on IBM DB2. But when I took a course on MSSQL, the emphasis was on 'click here to make this happen'. Or 'do this, it works (until such time as it doesn't work, then you are on your own.)'

Thanks
I agree learning the internals is a good way to start.

Thank you
