Version History Records of Base Table Rows in the Halland Dataset Collection

The table under discussion is a history table, storing the version history of its base table rows. It is part of a dataset collection from Lantmäteriet (The Land Survey of Sweden), which is a significant source of geographic data in Sweden. This table is unique as it contains two additional columns for tracking the version history of its base table rows. These columns record the dates when a row was extracted from the data source and when a new version of the same row was extracted. If the latter date is null, it signifies that the row is the most current version.

The table contains a mix of data types including geographical data. The geographical data, originally in shapefile format, was transformed into a final geographic format for easier use. The shapefile format is a popular geospatial vector data format for geographic information system software, capable of storing points, lines, and polygons.

Data from this table can be leveraged in various ways. For instance, by using the version history, one could track changes in geospatial data over time, providing a temporal dimension to the analysis. This could be useful for environmental studies, urban planning, or even socio-economic research. Furthermore, the unique combination of the start date and row number can be used to conduct a detailed audit of data changes, which can be critical for data governance and data quality management.

Finally, the geographic data can be used for geospatial analytics, allowing for a visual representation of data points on maps. This can be particularly helpful in fields like logistics, disaster management, and real estate where geographic location and attributes are of prime importance.
