I am not affiliated with this project in any way, except as a
spectator. I have tried the on-line demo, and am quite impressed.

Overview

At its current (and simplest) form, OpenI provides a web-driven
interface to build and publish interactive reports from OLAP data
sources. Going beyond that, OpenI aims to provide consolidated analysis
from all the key data components of an intelligent application,
including:

OLAP data sources
Relational databases
Statistical data models
Data mining models Demo


Our key goal is to take away the complexity of creating and publishing
reports for business users. OpenI does this by providing a clean,
intuitive interface to connect to different types of data sources, and
to publish web-based interactive reports. If you want to build
web-based intelligent applications that interact with your OLAP data
sources, we want OpenI to be a viable option for you.
