Informix Warehouse Accelerator (IWA) makes Informix run OLAP queries with lightning speed. News, hints and tips are provided in the blog by the Informix developers working on the product.
While the complete blog of this group is readable to the public, the group itself is not open to the public for membership.
In order to keep with the premise that all content is provided by members of the Informix Development organization within IBM, membership in this developerWorks group is only open to people from this organization. Within this developerWorks group there is no other activity besides publishing the blog entries.
