Moving Data from SQL Server to Teradata

Hi,

I'm not sure if I posted this in the right forum, but here goes.

I need to load (basically copy) tables from a SQL Server application and load those tables to Teradata. I can access the tables thru SQL Assistant now, but am not sure how I should set up this "copy" from one platform to another. There are 100+ tables that I need to copy, and this copy will be done on a regular basis (weekly or monthly) so a manual process is not ideal.

Someone suggested using OLE Load to do this copy. Is this the best way? Can OLE Load be set up to run in batch mode? If so, how?

Someone also mentioned SSIS. I know nothing about that, so don't even know where to begin reseraching this option.

Is there a better way?

My customer is extremly limited in technical ability, so I will have to come up with the solution. I will not have the ability to do anything with the SQL Server other than just read the tables. The solution must be done on my side in the Teradata world.

Any and all help is really appreciated!

Thanks!
Paul

Re: Moving Data from SQL Server to Teradata

Hi Paul,

SSIS is SQL Server Integration Service, a kind of ETL Tool of Microsoft. If you just would like to load data from SQL Server to Teradata, it is not a bad choice. There are some available SSIS packages which you can just reconfig the connection and ready to use. Here is a very good projects from Microsoft that you can download all the packages: http://www.microsoft.com/sqlserver/2005/en/us/project-real.aspx

Another solution in pure Teradata environment is using TPT script Teradata Parallel Transporter which allow several parallel thread of loading data to Teradata.

Hope you can offer the best solution to customer :)
