Version History of Base Table Rows in Norrbotten Dataset Collection

The table in question is a history table, which forms part of a dataset collection. It contains the version history of its base table rows, making it unique in its ability to track changes over time. The table is made up of several columns, which include specific dates to indicate when a row was extracted from the data source and when a new version of that same row was extracted. This allows for precise tracking of changes in data over time. In cases where the end date is null, it signifies that the row is the most recent version.

Unique identification of each row is achieved through a combination of the date of extraction and the row number. This history table contains two additional columns compared to its base table to accommodate for the start and end dates.

This table also contains geographic information, which was originally in shapefile format - a simple format for storing the location and attribute information of geographic features. This geographic information has since been transformed into the final geographic format from the original shapefile format.

The data for this table is sourced from the website of Lantmäteriet (The Land Survey) in Sweden.

The data in this table can be used in a variety of ways in data analytics. For instance, changes in geographic features over time could be tracked and analyzed, which would be valuable in environmental studies or urban planning. Similarly, the historical data can be used to identify trends, anticipate future changes and inform strategic decisions. Moreover, the geographic data can be used in geographic information system (GIS) applications for spatial analysis and visualization.
