I am looking for a database that could handle (create an index on a column in a reasonable time and provide results for select queries in less than 3 sec) more than 500 millions rows. Would Postgresql or Msql on low end machine (Core 2 CPU 6600, 4GB, 64 bit system, Windows VISTA) handle such a large number of rows? A technique I use to query the MOST RECENT rows in very large tables (100+ million or 1+ billion rows) is limiting the query to "reading" only the most recent "N" percentage of RECENT ROWS. This is real world applications, for example I do this for non-historic Recent Weather Data, or recent News feed searches or Recent GPS location data point data. Join Dennis Taylor for an in-depth discussion in this video, Applying conditional formatting across rows of data, part of Excel Tips Weekly. Say you’ve got a table with millions or billions of rows, and you need to delete some rows. Deleting ALL of them is fast and easy – just do TRUNCATE TABLE – but things get much harder when you need to delete a small percentage of them, say 5%. Stall Speed at Clmax=x.xx - This appears only on the in-flight analysis, and only if the wing area and airframe weight were specified for the model. It indicates the range of speeds which are at or below the aircraft's stall speed at the maximum lift coefficient (i.e. the speed below which the aircraft cannot fly). Important. Choosing a transaction isolation level does not affect the locks acquired to protect data modifications. A transaction always gets an exclusive lock on any data it modifies, and holds that lock until the transaction completes, regardless of the isolation level set for that transaction. Note.

A game theory curiosity: what is the role of infrastructure? It’s interesting that though Assad, ISIS, China, Russia etc all know that computers & networks are heavily pwned by their enemies like the USA, they still can’t bring themselves to take it down or stop using them.
