Is there an in memory OLAP (slice and dice data) Java library. (The equivalent of Microsoft Analytic Services). Especially would like to hear if anyone has used one for real.
www.icCube.com is a JAVA in-memory OLAP server. It can be either embedded in your application or you can access it via our XMLA client library or any other XMLA JAVA client library. Note that the engine itself is quite light. Yes, it is used in production.
