Processing and data storage in DB

Information from meters is stored on the server through rsync on a copy of the measure files. This information has the following properties:

  • may contains errors
  • may be inconsistent: some minutes does not exist or be repeated
  • contains raw values, there are only direct measures
  • its access and use are tedious

For this reasons, some R scripts have been developed that perform the following actions:

  • clean errors and process them
  • ensure consistency by creating a continuous time reference
  • prepare the desired raw values to be stored and process new information from these raw values
  • store this information in a MySQL DB
