Editorial - A Computer Goes to College |
|||||||||||||||||
A college education is something many parents desire for their children. It's almost expected that all school children in the US will grow up aiming to attend some university. Not all kids will follow this path, and whether it's the best choice for most of them is debatable. Apparently IBM thinks it's little one is ready to go as well. A Watson supercomputer is being sent to Rensselaer Polytechnic Institute in New York to go to school. In it's quest to defeat the Jeopardy champions, this type of computer was fed a tremendous amount of information from general sources. A clone of Watson received specialized medical data to help doctors diagnose patients better. This last incarnation of the computer system will be fed information from various researchers in different fields at RPI. What will come out of this, experiment nobody knows. The Watson system going to RPI seems modest in size, with 15TB of storage reported. That seems small. The specs posted for the Jeopardy system include 2880 cores and 16TB of RAM. That's not the size of system many of us every get to work with. The software, called DeepQA, is the core of the system and allows it to process vast amounts of data and make connections between the data to answer questions. 2880 cores is a lot, as is 16TB of RAM, but there are SQL Server installations that are getting close, with 2TB of RAM. Some Parallel Data Warehouse installations with hundreds of cores. I can foresee a day when Watson-sized systems are more common. Perhaps we'll even get a Watson version that helps us better analyze the data we work with today, a version that works closely with the DBA-turned-data-analyst to extract information from the petabytes of storage we'll have accumulated. » Join the debate, and respond to today's editorial on the forums The Voice of the DBA PodcastsWe publish three versions of the podcast each day for you to enjoy.

Question of the Day |
|||||||||||||||||
|
Today's Question: I run this code:
CREATE VIEW MyView AS SELECT * FROM dbo.MyTable GO SELECT * FROM dbo.MyView
I get back the one column in MyTable in my result set. I then execute:
ALTER TABLE MyTable ADD x2 INT GO UPDATE MyTable SET x2 = 1 GO SELECT * FROM dbo.MyView However I only receive the one column with the same result set as in the first code block above. What do I need to run to ensure I get all the data back from the view? Think you know the answer? Click here, and find out if you are right. This question is worth 1 point in this category: T-SQL.

Which of the following query will provide different answer? Statement A. SELECT (45 * (9 - 5 + 8)- 36 / 4) Statement B. SELECT (45 * (9 - (5 + 8))- 36 / 4) Statement C. SELECT (45 * (9 - 5 + 8)- (36 / 4)) Statement D . SELECT (45 * ((9 - 5) + 8)- 36 / 4)
Answer: Statement B Explanation: The answer for all statements except Statement B is 531. The result of statement B is -189. This shows how brackets changes the precedence of computing. Ref: http://msdn.microsoft.com/en-us/library/ms190276%28v=SQL.90%29.aspx |
