Version History of Base Table Rows in Örebro Dataset Collection

The 'clc12_66e_so__history' table is a historical table that forms part of the 'orebro' dataset collection. It originates from the 'Lantmäteriet' website, based in Sweden. This table is unique in that it contains the version history of its base table rows. This is made possible by two additional columns that record the start and end dates of each row's extraction from the data source. A unique identifier for each row is created through the combination of the start date and the row number. If the end date of a row is null, it signifies that this is the most recent version of the row.

The table also contains geographic data, initially in shapefile format, which has been transformed into a final geographic format. Shapefile is a format for storing the location and attribute information of geographic features, which can be represented by points, lines, or polygons.

This table can be incredibly useful in data analytics. For instance, one could track the evolution of geographical features over time by comparing different versions of the same row. Alternatively, the data could be used to analyze patterns in the extraction dates of the data, perhaps shedding light on the frequency or timing of updates to the source data. Furthermore, the geographic data could be used to create visual representations or maps of the data, allowing for a more intuitive understanding of the information.
