OPENI
OPENI是一款基于WEB应用的开源OLAP报表系统，功能如下：

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

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.
