As the title suggests this post refers to a workshop that will be held in Lisbon on May 26-28 about IDS 11.50 (Cheetah 2).
As this will be a local Workshop the rest of the post will be in Portuguese. Information about other locations can be seen at the IIUG site

Just a very quick post to echo an IIUG announcement. If you're a member of IIUG you can do an Informix V11 certification preparation test. This will be a test similar to what you'll find if you want to do the 918 exam, which will allow you to be certified on Informix.
