Database Features

• number of supported databases: unlimited
• types of supported spectra: all spectral types which are supported by Epina ImageLab
• max number of database entries: limited by available disk space (1000 entries require typically between 20 and 30 MB, depending on the type of the spectra)
• design size of database: 100000 entries (this is not a hard limit, just an optimisation criterion for the database software)
• predefined properties:
  • unique database item identifier
  • date/time stamp
  • molecular formula (max. 20 different elements)
  • author or source of the spectrum (max. 255 characters)
  • name of item/spectrum/substance (max. 255 characters)
  • comment (max. 255 characters)
  • keywords for indexing the spectra (max. 255 characters)
  • class number (integer value)
  • spectral type
  • position of the spectrum if taken from an image, or the area in the case of an mean spectrum
  • status flag (16 user-definable binary flags)
• user-defined properties: unlimited (depends on available disk space)
  the user can define any number of additional database fields ("properties")
• types of user-defined properties: string, double, integer, logical tri-state (yes-no-unknown)
