In case you had not heard there are two new analyst reports out on Informix - one from ITG and the other from Forrester. Both these reports are very favorable to Informix and I encourage you to read them. The ITG report compares the cost of Informix over time compared to SQL server and concludes that Informix is by far the less expensive of the two, about 1/3 less in fact. The ITG report can be found here: ITG report
The Forrester report focuses on the cost of Informix for a hypothetical global retailer with 4,000 instances of Informix. The conducted interviews with many of our global retailers including some of the biggest ones and concluded that Informix offers the following key strengths:
• Minimal DBA requirements that allowed high levels of DBA efficiency and a shift away from reactive to proactive functions.
• Cost avoidance of both planned and unplanned downtime.
• High levels of system performance resulting in lower capital investment costs.
