description

Man betrachtet das flüssige Wasser, das sich bei Niederschlag (Regen, Schnee, Hagel, Nebel usw.) in einer definierten Zeitspanne in einem nur nach oben offenen Gefäß mit definierter horizontaler Öffnung sammelt. Als Niederschlagsmenge bezeichnet man das Volumen der Flüssigkeit bezogen auf die Fläche der Öffnung und gibt sie an in Liter pro Quadratmeter bzw. Millimeter (1L/m² = 1mm).

synonyms
Niederschlag, Rain, Regen

Parsing data File

Estimated Time:

Why does it take so much time?

While parsing a file, the database has to perform various tasks, some of them needs a lot of CPU and memory for larger files.

  • preprocessing: means automatic detection of headlines, table body, format values or csv-separators
  • copying: means read the file cell by cell and copy all elements to the database. During this format settings can be calculated (for example iso-time)
  • analyzing: check out for different data types (can be time, numeric or text)
