Many data sets have been collected by Auke Bay Laboratories over the years. For our purposes, a data set is defined as a collection of data records organized around a common attribute. A data set is created by converting raw data into records. Raw data are collected by the trained observer, and then converted into processed data by one or more actions. A record is a collection of processed data organized around some common attribute, such as date of collection, locality of collection, individual animal and so forth. A data set is a collection of those records.
