-==== SysMetrics database creation ====
-Since I started with Windows, I will present a SQL Server database script first. Please note that metrics data is typically write-once and read-only, so column-store tables are perfect fits. InfoBright's Community Edition is a column store database engine and it is free. I recommend using it and I really doubt that we will need to purge historical metrics data if we use that. Or at a minimum, we would be able to keep that history much longer.
-Here is the ER diagram of the SysMetrics database. For now there are only 7 tables involved under the Windows schema, so it is pretty easy to understand and query.
-{{ wiki:SQLServerSysMetrics.png }}
-Note that syntax highlighting is not completely correct, but the script is just fine.
