Version History of Base Table Rows in Gavleborg Dataset Collection

The 'History' table is a fascinating compilation of data, sourced from the Swedish website, 'Lantmäteriet'. This table forms a crucial part of a larger dataset collection, playing the key role of preserving the version history of the base table rows. Each row in this table is uniquely identified by a combination of the date of extraction and the row number in the raw data.

The table is enriched with timestamps indicating the start and end dates of each row's validity. An interesting feature is that if the end date of a row is null, it signifies that the row is the most recent version. This temporal dimension of the data offers a unique opportunity to track changes over time and understand the evolution of the data.

Moreover, the table also stores geographic information, which has been transformed from the shapefile format. This format is a widely used standard for storing geometric location and attribute information of geographic features, which can be represented by points, lines, or polygons.

The potential uses for this table in the realm of data analytics are vast. For instance, one could track changes in the geographic features over time, providing a dynamic perspective on spatial data. Additionally, the unique combination of row number and extraction date could be used to study the frequency and nature of updates to the data source. Importantly, the presence of version history can aid in maintaining data integrity and conducting detailed audit trails.
