Help me put Oracle terminology into SQL Server terminology [closed]

Question

My company is now supporting Oracle for the first time, and most of my colleagues are SQL Server developers who haven't really worked with Oracle. I'm a little bit familiar with Oracle, but far from a genius on the subject. Unfortunately, that is enough to mean that I know more about Oracle than most of my co-workers, so I find myself constantly struggling to explain concepts I'm still learning myself in terms that people who aren't familiar with Oracle at all can understand.

The biggest problem that I run into is in knowing how SQL Server terminology translates into Oracle terminology. I understand that there's not a direct 1:1 mapping of terms, but it would be helpful to be able to know how to put Oracle concepts into SQL Server terminology and vice-versa when talking to my SQL Server-centric co-workers. Can someone tell me the best way to put these SQL Server terms into Oracle terminology?

• database
• instance
• schema

And conversely, how to explain these Oracle concepts in SQL Server terms?

• tablespace
• database
• listener
• service name
• SID

Answer 1

Oracle/SQLServer:

• tablespace = doesn't exist
• database = doesn't exist
• instance = instance
• schema = database
• listener = doesn't exist
• service name = database name
• SID = database name
