SBOP BI Platform Middleware/Warehousing

Hello Experts,

Do you have any resource or reference for middleware used in terms of Sybase IQ, SAP BW (legacy-not BW/4HANA), and MS SQL? We have poured through the SAP documentation, and they all seem like viable options for middleware/data warehouse/reporting DB's with respective pros/cons. However, we do not want to get in a bad position halfway through the implementation (i.e. any major implications or limitations). Any help and/or outside perspectives are much appreciated.

For example, are there white-papers, or analysis for the different integration options above? I've exhausted SAP material but maybe I am missing value information, such as customer testimonials or references, etc?

Solution: the newest BI Edge 4.2 package (with Data Integrator to facilitate ETL and assist with modeling and Sybase IQ cores included as an option).

I can provide further details upon request. Thanks.

Best,

Jake
