This is an Open Source ETL solution from Talend, a member of the Open Solution Alliance.

The architecture is similar to Oracle Data Integrator and WhereScape Red. I recommend all three products to be included in an ETL solution selection task when it is required.

Informatica is the tool of choice for an implementation of Siebel Analytics Application/Oracle BI Application. It is the leader in the market and it is a great product reason why Siebel chosen to partner with it. Nevertheless, these new products specificall WhereScape Red, are offering embedded best practices for multidimensional modeling and data warehouse design, part of the new paradigm of Service Oriented Architecture technology of which Siebel Analytics Application is a good example of it.
