Highlights: Presenting the 2015 IIUG Board of Directors
Welcome to the International Informix Users Group (IIUG) Insider! Designed for IIUG members and Informix user group leaders, this publication contains timely and relevant information for the IBM Informix community.
The April Insider is a little late. I had a busy week at the IIUG conference in San Diego and then a long and tiresome flight home.
The IIUG 2015 was outstanding as usual. 85 high quality technical sessions, 10 half-day tutorials, Ask the Experts panel, two keynotes, free certification, demos and more. There is no other matching event for an Informix technical professional. I learned a lot, but my greatest pleasure was meeting old friends and making new ones.

"It" is OVER...?
OLAP (On-line Analytical Processing) is available as new SQL functionality in Informix Dynamic Server 12.10. It is done using an OVER() function to examine subsets of rows in the result set of a query or subquery. These subsets are known as OLAP Windows expressions. The results can reveal patterns, trends, or exceptions in the data.
A simple way to understand this SQL functionality is to visualize it like a clear window on an envelope — you can see a block or range of data by looking through the window at the subset returned under the window. The functionality allows application developers to compose analytic business queries such as moving averages, moving calculations, or moving sums over an interval. Aggregations and ranks can also be reset as column values change, and ratios can be expressed in simple terms.
The syntax occurs as three variations of the over() function, which are provided by way of OLAP numbering, OLAP ranking, or OLAP aggregation. For more information on OLAP windows check the online documentation.
Just in case you are not aware, some time ago IBM created a public website to collect the requests for new features directly from users. The RFE (Requests For Enhancements) website is included in developerWorks. You can access it here.
Once you logged in with your usual IBM ID, choose "Information Management" in the Brand dropdown box and "Informix Servers" or "Client Products" in the Products dropdown box.
The interesting thing is that any request, including your request, if you place one, are submitted to be voted on. This means the RFEs that receive more votes have a greater chance to be considered by the architecture and development teams for further consideration. In other words, this IS the opportunity to provide enhancement ideas even if you are not the biggest IBM customer on the planet Earth.
Some RFEs will be of great interest, others will not seem useful to you. This is why your opinion is important. Do not hesitate to vote and place comments!
The idea of the RFE corner is to provide a digest on new Informix RFEs and make those RFEs more visible and accessible for the community, so that you can vote for them in a faster and easier way. By participating actively in this website, IBM will have solid and useful elements from the customer base to introduce new functionality to Informix product.
Also in the area of IBM website, a new functionality has been released: MyNotifications. You will want to register this webpage in order to receive the notifications of your choice (new product defects, new patch release, new versions etc..., on the frequency of your choice (daily, weekly). I have registered and will definitely keep registered, due to the value of the information delivered.
Annual IIUG features survey
Before checking this month's list, do not forget to complete the annual IIUG Features Survey that we have created for you. This survey is a summary of this past year's most significant new features requests from the RFE website for Informix products.
By casting your vote for your favorite Informix new features, you will give extra momentum to those RFEs and contribute to turning them into actual Informix features.
This survey should not take you more than 10 min. The IBM Lab wants to hear from you, don't miss this opportunity!

New RFEs for April 2015
The month has been rather productive in terms of new RFEs let's take a look at them:

Do not forget to vote for one or several of those RFE's if they fit your requirements. The more vote, the more chances that the Dev Team will seriously consider the request.
You can access each RFE by clicking on the above links. At the bottom of each RFE page you will find a hyperlink to vote for it. You will see the Request stats, including number of votes for this request, on the right side of the request page. The more votes, the greater the chance an enhancement will be addressed by the Development Team, taking into consideration the general interest.
Take some time to examine the full list and vote for the enhancements you would like to see implemented.
