Is anyone hiring at the moment? Looking for a London-based BI focused role
tonyrogerson Wed 12:46PM
@philcr I'd really like to see Surface with a 2008 R2 demo on it taking full advantage of the kit - that would be cool! #sqlfaq
tonyrogerson Sun 10:14AM
Time for a brew - am reading on the SQL Server Modelling stuff and "M" - don't see where it fits to be honest #sqlfaq
tonyrogerson Fri 8:13PM
@Plip Should have used DAS and disk replication - commodity simple kit always the best approach (usually) #sqlfaq
tonyrogerson Fri 4:52PM
Ashwani Roy and Chris Testa-O'Neill are doing a 30 minute Q&A panel at the 17th March UG even - cool #sqlfaq
tonyrogerson Fri 3:13PM
Posted a blog http://bit.ly/afepEy that describes what Granularity is #sqlfaq
tonyrogerson Fri 12:24PM
7th May 1pm - 1.45pm http://bit.ly/c4UmAP I'm going to do a webcast on Normalisation - vender neutral #sqlfaq
tonyrogerson Fri 12:02PM
Just helped a friend take her first steps in SQL Server #sqlfaq over LiveMeeting; dam "namespace error" on SSRS on the install though :(
tonyrogerson Fri 10:32AM
Thinking about my Denormalisation/RElational Theory talk for SQLBits #sqlfaq; so much to cover - so little time.
mladenprajdic Fri 10:22AM
@tonyrogerson i don't know how useful the #sqlfaq is but there is #sqlhelp that is used and has quite some traffic.
tonyrogerson Fri 10:17AM
Whats the point using DISTINCT (tuples will b unique-I get that), but still keyless - what have you achieved in "relational" terms? #sqlfaq
tonyrogerson Fri 10:09AM
In CJ Date's book SQL and Relational Theory he talks about having DISTINCT on every query - that would be interesting #sqlfaq #infooverload
tonyrogerson Fri 7:39AM
17th March Business Intelligence event is now full - we've over 100 registered now, there is a reserve list in operation #sqlfaq
