CVHistorian is the first industrial relational database. CVHistorian provides a large amount of data to be inserted into databases such as SQL Server. We have tested CVHistorian by inserting 11,000 records per second. CVHistorian also provides tools to optimize your data. Here are some of the tools:

  Since CVHistorian is based on OPC, event driven methods are available.

  CVHistorian has tools to specify if the data inserted into the database should be calculated before actual insert occurrence. For example, you can specify that only max, min, or average values be inserted into the database calculated based on one second, one minute or one hour

  You can always insert data on pre-settable intervals (100ms – 24hours)

  The built- in functions allow you to scale your raw data before being inserted. No scaling is required by your SACADA/HMI or other database viewers.

  Traditional data management routines also included:

• Deadbanding
• Rounding
• Clamping
  

Configuration & Troubleshooting Tools:
  OPC Server browsing (collect data from multiple sources)
  Simple configuration interface
  Performance monitoring tool and error logging

Redundancy:
CVHistorian provides hot-redundancy with the capability of fail-over in 2 seconds.
  Typical Hardware (10,000 inserts per second):
  Processor – 2MHz (minimum)
  RAM – 512MB (minimum)
  Hard Drive – 10,000 rpm 80GB (optimized RAID-1)

Typical Software:
   Windows 2000/2003 Server (required for SQL Server)
   Microsoft SQL Server
