Version History of Base Table Rows in Jamtland Dataset Collection

The table under discussion is part of a dataset collection and serves as a history table. This table keeps a record of the version history of its base table rows. The table is distinguished by two additional columns that track the start and end dates of each row's extraction from the data source. If an end date is null, it indicates that the row is the most recent version.

The table is sourced from the 'Lantmäteriet' (Land Survey) website in Sweden. Unique identification of each row in this version history table is achieved through a combination of the start date and the row number.

Interestingly, the geographic information in this dataset is derived from a shapefile format, which is a non-topological format utilized for storing the geometric location and attribute information of geographic features. Geographic features can be represented by points, lines, or polygons (areas).

This table can be a rich source for data analytics. For instance, it could be used to track changes in geographic feature data over time, thereby providing insights into spatial trends. The version history could also aid in debugging and error detection by providing a history of changes. Additionally, the geographic information could be utilized to perform spatial analysis or generate visualizations of geographic features.
