Subject Single Column vs Multiple Columns
Date Fri, 17 Dec 2010 16:49:47 GMT
I have a data model where each read and each write will read and write all data for a given
key.  Thus, does it make more sense to separate the data into multiple columns, or does it
make more sense to store all data in a single column?

My understanding is that breaking data into multiple columns is an optimization for reading
and writing a single column. If all data is updated for every write, and read for every read,
then having all data in a single column offers better performance, is this a correct assumption?
