Version History Data of Base Table Rows in Sodermanland Collection

This history table is an integral part of a dataset collection, which traces the version history of base table rows. The table allows for precise tracking of data changes over time, with specific columns indicating the date a row was extracted from the source, as well as the date when a new version of the row was obtained. If the latter column is null, this indicates that the current row is the most recent version. A unique identifier for each row in this version history table is formed by combining information on the extraction date and the raw data row number.

The table also includes geographic information, originally in the shapefile format, which has been transformed into the final geographic format. This means that geographic features in the dataset can be represented by points, lines, or polygons.

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

As for possible uses in data analytics, this table can provide valuable insights into trends and changes over time. For instance, it could be used to track changes in geographic features, identify patterns or anomalies in the data history, or effectively manage and update the data in line with changes in the source material. The geographic information could also be utilised in spatial analysis, enabling the visualisation of data on a map and facilitating a better understanding of spatial patterns and relationships.
