The history table in question is part of a dataset collection originating from Västerbotten, Sweden. This table functions as a historical record, containing the version history of its base table rows, which allows for tracking changes over time. It also has two additional columns compared to its base table, which are used to indicate the start date when the row was extracted from the data source and the end date when a new version of the same row was added. In cases where the end date is null, it indicates that the current row is the most recent version.

Each row in this table is unique, identified by a combination of the start date and the row number. The data in this table also includes geographical information, transformed from the shapefile format, a simple, non-topological format used for storing the geometric location and attribute information of geographic features. This geographic information could be represented by points, lines, or polygons (areas). The table's data is sourced from the website of 'Lantmäteriet' (The Land Survey of Sweden).

Examples of how this table's data could be utilized in data analytics include tracking changes in geographic features over time, understanding patterns and trends in the version history, and analyzing the frequency of updates. Furthermore, the geographical information can be used in spatial data analysis to study geographical patterns and phenomena.
