Fastest way to copy a Database to another database

I am creating a project where I am taking data from Oracle tables and populating SQL Server. I have scripts that will create the tables in SQL Server. My question is what is the most efficient (Quickest) way to accomplish this.

� 

As a Use Case, I� am doing this with a few tables from Microsoft's AdventureWorks datebase. I am copying rows from a few tables to� temp tables.� My code works, but tables that have say 19,000 rows of data take up to 20 minutes to insert. Is that normal?

� 

Here is my code for the population of the� Person.Address table (from adventure works), minus the creations scripts that create the temp tables. Would it be faster using DataAdapters? Or any other methodology?
