How to Prepar for Data Mining

There is a new article by Eric King of The Modeling Agency on How to Prepare for Data Mining. It has some interesting points on various aspects that you would need to look out for.

I think some of the important things is that you need to plan such a project carefully, that you understand what you can get out of a data mining project, and have an appreciation of the type of techniques/technologies involved.

Together we are offering a number of training courses on Data Warehousing, Data Mining, Oracle Data Mining and Master Data Management.

I will also be regularly posting on their blog on various topics relating to Data Mining.

Welcome to my Data Mining Blog

I will post my postings from various other blogs and locations here. They will be all based on my view of data mining and performing data mining in Oracle.
