RE: What tools for Oracle Data Warehouse ETL

Steve,

you said:
"Ideally you'd want to avoid sql-loader like the plague and have the product load directly. Every project I've been on that used Oracle's loading software got bottlenecked to the point of severe pain."

Just curious, why was using sql-loader in the process so painfull - or was there an alternative that was so much better?

Inquiring minds want to know.

You left out Ab Initio. Probably the best thing going for heavy-duty processing.

Ideally you'd want to avoid sql-loader like the plague and have the product load directly. Every project I've been on that used Oracle's loading software got bottlenecked to the point of severe pain.
