The wave chart of this paper shows the net profit of three book suppliers in 2008 year by month. Individual net profit values tell which vendors are doing well, and wave charts help identify trends that follow numbers: Seattle and Houston have fallen in summer sales, usually their profits have been climbing, and Richmond has been underperforming in addition to the last one months.

Last year, when I was in Seattle for the opening of SQL PASS Summit 2012, Microsoft announced that the next SQL Server version would be accompanied by a Hekaton-coded memory database engine. Now, with the advent of 2014CTP1, we can final

According to researchers at the University of California, San Diego, purchasing a faster switch may be the only way to improve the network performance of the entire data center. These researchers proposed this week a network architecture that enables commercialized Ethernet switches to provide better performance at a lower cost than 10-Gigabit Ethernet switches.
