For RamKumar and Mike -> (i made some change on the 6th paragrah, from my original post).

For the license-discuss owner. Can we proceed with this kind of discussion (about a
new development regarding Datawarehouse) on this list?

So,

The SUN Microsystems and OMG are working together in new specifications regarding datawarehouse.


On the OMGs side (www.omg.org), they are working on CWM (Common Warehouse Model). This
is a specification regarding DataTransforming. And I don't know if the actual spec has
something about OLAP (Cubes).

On the SUNs side, they are working in some developements, DataMining, OLAP, MetaData,
and they will use the spec of OMG (CWM), as you can see on their website (http://java.sun.com/aboutJava/communityprocess/jsr/jsr
069 jolap.html)

I am part of this Expert Group (JOLAP). On the JOLAP, all informations are confidentials,
but I have some other (good) knowlodge about OLAP. And I have worked with JOLAP about
7 years (at this time the OLAP name doesn't exist).


My point of view of OLAP is to be free about the implementation of the server. We should
be able to construct a front-end and use that with any OLAP Cube Server. And I believe
that is necessary a OLAP Cube Server. My CubeServer is a MetaModel based on relational
tables (not ROLAP). We have built a MOLAP over Relational. Its like a binary Data-Structure
serialized in Relational Tables. This infra-structure enable us to use any relational
database as a OLAP Server. Its sound good, because the users doesn't have to understand
a new kind of server, and help the entrance on a new Customer.


So, that's was my job. Now, I'm working on a new OLAP Server and a OLAP client based
on Java and HTML. I will have a version done on three months (very simple version, but
this version will help my current customer). I believe that with a short investment
of time, we can do a good OLAP Product.


Lets start a discussion as Mikde said!

    Dear All,

    Im already in a project, which I will be able to run DataWarehouse on any platform.
The only decision that we will need is to open the code sharing that, and improving
the product.


    Believe-me, the idea about this data-warehouse is a good idea. We will have a code
based on OLAP Providers, which we will be able to open any cube on the server. I have
used a lot of plugin points (in Java), to be independent from the DataWarehouse OLAP
Provider.

    I have a lot of knowlodge about OLAP, but Im so far from you area (Im on Brazil),
and a face to face meeting should not work to myself.


    Please, let me know if someone has interest about my ideas.

      Hello Forums @ OpenSource: 


      By way of introduction my name is Mike Crispi, 2 weeks ago I sent out an 
      email asking group members if they were interested in a data mining and 
      warehousing project. To my surprise the feedback was very positive and I 
      would like to start with an open discussion platform in order to start this 
      project in motion. 

      If you have any good ideas about the content, direction, management, or would

      like to share your expertise running a previous project, please write it down.


      If someone would like to volunteer and setup a time and location for our 
      first session online, please feel free to post.  We will follow your 
      direction.  When referencing this project, use the title 21st century mining.


      Thanks, 
      Mike
