A look back at 2008 and some crystal ball predictions…, byTammi Kay Geroge, from SASBlog*/
Major Data Warehousing Events of 2008 (and Predictions for 2009), by Michael Schiff, from TDWI,
Major Data Warehousing Events of 2008:
- Everyone had an appliance story
- Industry consolidations continued
- The recessionary environment encourage further BI developments
- Open source grew
Predictions for 2009:
- Further industry consolidation(Informatica by HP, SPSS by SAP)
- Cloud computing will come down to earth
- Open source growth will accelerate
- The IT world will become greener
- Major emphasis on solutions rather than tools and technology
SAS and Teradata Partnership: Press
- Leading Companies See Value in SAS and Teradata Partnership
- SAS and Teradata Unveil Advantage Program to Bring Powerful In-Database Solutions and Services to Customers
- SAS and Teradata Enter into Strategic Partnership
In BI industry, the pure players such as SAS, Teradata and Microstrategy, need to demonstrate their indispensable values against the megavendors, IBM (acquired Cognos), SAP (acquired Business Object), Oracle (acquired Hyperion) and Microsoft. Teradata is solely focused on enterprise data warehouse. SAS, dominating in business analytics (e.g. advanced statistics and data mining), will check and balance the BI industry due to the private-hold structure. SAS and Teradata Advantage Program partnership, includes wide business lines, such as Analytics, AML (Anti-Money Laundering), Credit Risk, Enterprise Intelligence and Optimization Services. I think It’s a effective way to learn from each other in mutual emulation and counterbalance the concentration market.

How to know the boys and girls’ real demands around the world? and how to predict their demands in next Christmas?
How to purchase toys and goodies with a balance of costs and profits? and how to deliver them more efficiently?
There are lots of questions in the list of Santa, CEO of Santa’s Workshop. SAS’s marketing staff held a very creative champion for the coming Christmas. You can watch the interview with Santa in youtube.com, or read the success story about Santa, Santa’s Secret: Magic? No. It’s SAS(R) Business Analytics.
If You Can Make it Here, You Can Make it Anywhere: On What Makes a Good Business Analyst by Rajan Chandras
In the latest post, What Makes a Good Business Analyst?, Rajan Chandras cites some soft items from Forrester’s Business Analyst Assessment Workbook:
- Ability to think abstractly, identify patterns, and generate ideas and solutions
- Understanding of when and how to escalate issues or needs
- Understanding of and ability to delivery the appropriate level of detail needed for each task
- Interest in exploring and understanding new concepts and topic areas
- Emotionally invested in the work
- Ability to learn by shadowing stakeholders
- Ability to clearly articulate technology in terms stakeholders can understand
- Understanding of the organizational culture and its impact on processes and projects (this one seems obvious, but the latter phrase is more profound than might seem at first glance)
- Ability to drive a decision analysis and selection process
- Ability to recognize patterns in requirements and categorize them appropriately
What’s more, there are some suggestions by Rajan Chandras himself:
- Know the organization’s external environment: its competitive position, current state of the industry, geographical & social factors, etc.
- Know the organization’s internal environment: its financial position, organization culture, IT maturity, etc.
- Adapt to the needs (your language, dress etc.), but be yourself. Imperfect, yet genuine, is fine; falsity comes through easily, and will destroy your credibility in no time.
No doubt, no boss can reject such a perfect analyst. But I’m afraid these standards are suitable for every professionals. That is to say, they create a model to explain everything. It is too universal to be served as a good filter to select the most proper analysts. She or he may more marketable in any other business line.
Data Mining in Stock Market? Is it crazy? or is it just a hopeless try? Every mentor in mathematics and finance educates us that the stock market is too chaotic and sentimental to use mathematical models. Most of all gift rock scientists are concentrated in the study of interest of rates and fixed income securities. It sounds profitable to use mathematical and statistical models to predict the price of stock, but there are little successfull stories.
I know I might hold some academic doctrines, so I have interest to monitor any effort to try to forecast stock prices using data mining techniques. Some links from a popular data mining blog , Data Mining Research, are listed as follows:
