Charter of comp.databases.olap:

This usenet newsgroup will discuss the issues encompassing On-Line
Analytical Processing, as defined by E.F. Codd of Codd Inc. in
his recent white paper entitled "Providing OLAP (On-line Analytical
Processing) to User-Analysts: an IT Mandate".

Topics which could be discussed in this newsgroup include
multidimensional databases, multidimensional analysis tools and
techniques, decision support systems (DSS), executive information systems
(EIS), data warehousing, data marting, and a host of other related
topics. In general, OLAP is about getting data out of transaction
procesing systems and turning it into information. A more complete
description of the Codd paper on OLAP is given below, along with
additional references that I have found to be helpful on this topic.


In August 1993, Codd and Date announced a major breakthrough in business
computing with 12 rules for On-Line Analytial Processing (OLAP).  
Developed by Dr. E.F. Codd, with colleagues Clynch Salley and Sharon
Codd, OLAP is defined as the dynamic synthesis, analysis, and
consolidation of large volumes of multidimensional data.  Dr. Codd is the
founder of Codd and Date, Inc, and is the inventor of the abstract model
and the 12 rules for relational technology.

With OLAP, Codd and Date has established and clarified a significant area
of business data processing and a new product category for
"multidimensional analysis" -- which are not adequately addressed by the
current combination of relational systems, spreadsheets, and query tools.  
OLAP involves the dynamic and extensive manipulation of unlimited
variables of data, and complements On-Line Transaction Processing (OLTP)
applications.  OLAP applications include rapid consolidations and
multiple scenarios of forecasts, budgets, product plans, capital asset
plans, sales analyses, and performance reports.  OLAP products make
multidimensional analysis easier and more efficient for business users.


There has recently been an explosion in industry interest in OLAP
concepts, techniques, and products.  This is reflected both in an
increase in trade press articles and commercial products which serve this
segment.  In the comp.databases hierarchy there has been a similar
increase in postings relating to the issues that would be covered by this

It is my belief that the increasing interest has been largely driven by
the realization that now that we have figured out how to stuff 1000 TPS
into a database, we need better tools and techniques to get the data out
in a form that analysts can use to solve business problems.  The intent
is for this newsgroup to provide a place to centralize issues, expertise,
and information relating to OLAP.


Topics appropriate to this newsgroup include but are not limited to:

     - Decision Support Systems
     - Executive Information Systems
     - Multidimensional Database Systems
     - Data Warehousing
     - Data Marting
     - Very Large Read-Only Databases
     - Multidimensional Front-End Tools
     - Sparse Data Models and Optimization Techniques
     - Multidimensional Analysis using Relational Systems
     - Limitations of SQL for business analysis
     - Parallelization and other methods to speed processing.
     - End User Query Tools
     - Ad-Hoc Query Tools
     - Business Reporting and Financial Analysis Tools

comp.databases.olap Charter

I recently heard of this newsgroup and thought that certain readers
might find the following of interest:

I am currently spearheading a proposal within our firm for an R&D
project into multidimensional databases.  We are currently looking
for outside business partners, either academic or commercial, who
might be interested in participating with us in such an endeavor.

If you are interested in partnering with us in a true research and

and I'll send you a one page abstract describing the project.  We
can take it from there.

Some firms have expressed interest in projects involving existing
software products, but funding will only be made available to us
for undeveloped technology, hence the "true" moniker.

While we have already been in contact with a number of organizations,
no cooperative agreements have been reached yet, and would
welcome inquiries from other organizations.

Thanks for the charter, Dan. I've been looking for something like this for
a long time. In fact, I used to work with Jim Dorrian, Bob Earle and Jim
Lodestro in the early 80's. Send my regards.

There are a few products you may habe overlooked:

Data warehouse - considering the # of times you mention Kimball, why not
Red Brick?
Also, in the data warehouse manager category, have a look at Extract! from
ETI in Austin and Inmon's Prism, as well as EDA/SQL from IBI.
In the multi-dimensional DSS/modelling realm, there is Holos and Gentium.
Also, I believe that Powers and Wilk (of FCS fame) have a product growing
in the UK, but I don't know much about it.

Keep up the good work!

I'm extremely happy to see this group, also. While I've not written any
papers on the subject, I've been waging a quiet battle in the workplace
to get our systems analysts to look seriously at the OLAP concept.  Any
information I can get that will aid in the battle is sorely needed!
