Weekly Update




1. Quote of the Week
The future in data modeling is Object Role Modeling (ORM). It is a far superior way to approach data modeling (compared to any record-based methods such as relational) that avoids all the pitfalls of "Table Think" and the necessity of normalization. --LinkedIn.com
2. To Laugh or Cry?
Types of database management system and their evolution
3. Online debunkings
4. Elsewhere

Silicon Valley SQL Server UG Presentation




"To Laugh or Cry?" Test Your Foundation Knowledge

Tuesday, January 20, 2015 6:30 PM

Microsoft
1065 La Avenida
Building 1
Mountain View, CA  (map)

You are a DBMS ace, able to squeeze every ounce of performance out of it. But how about your foundation knowledge, how good a grasp of data fundamentals do you possess? Are you a data management ace too?

The two are distinct and while the former is necessary for a career, it is insufficient for an informed, intelligent, reliable and productive data management practice. The industry is full of myths, misconceptions and traps and without foundation knowledge you are unable to see through them.

This is your opportunity to test yourself. If your instinct is neither to laugh, nor to cry at the contents of this presentation, education may be in order.

• How misconceptions that you are unaware of, lead you astray;
• Practical implications thereof;
• How foundation knowledge, scarce in the industry, is the only way to see through them.




Understand Property Rules & Domains

Analytics & SQL Tables



My December blog @All Analytics. 

Manipulating/extracting data from SQL databases and interpreting results without knowledge of what the source tables mean is almost certain to lead analysis astray. To ensure sensible analysis and properly interpreted results, the conscientious analyst may have to do some digging that requires basic database knowledge. Here's why.
