Data Integrator

We are presently working on integration of heterogeneous systems. I was searching for a tool which will meet our requirements. Of course, the entire work can be done in SQLLoader too. But still I had to satisfy myself that SQLLOADER is THE answer.
One of the tools I came across was the Oracle Data Integrator.
This appears to be a regular ETL tool with oracle-specific features built-in. I have decided to explore further about this product.
Features I like about this product (of course I would probably find many of the features in the competitors too, But still it is worth exploring):

• Automatic code generation (reduces learning curve)
• User/Developer specifies the rules to apply to the integration processes.
• Hooks to SOA
  
• Library of Knowledge Modules (including one for Salesforce.com)

Getting the right data in the right place at the right time is the key to a successful data integration strategy. Are I going have a hourly/periodic updates from the source; if so, how complex will it be to maintain the program generated?
Will be posting more details later.
