Historical Versions of Base Table Rows in Jamtland Dataset

The table in question is a historical record of data sourced from the website of 'Lantmäteriet' (The Land Survey) in Sweden. As a history table, it holds the version history of its base table rows, allowing users to trace the changes over time. This feature is particularly useful in tracking the evolution of the data, identifying patterns, and predicting future trends. It has two additional columns compared to its base table to accommodate this, one indicating when the row was extracted from the data source and another marking when a new version of the same row was extracted. If the latter is null, it signifies that the row is the most recent version.

The table also has a unique identifier for each row, formed by a combination of the row's extraction date and its number in the raw data from the source. In addition to these structural features, the table contains geographic information transformed from the shapefile format, a simple format for storing the geometric location and attribute information of geographic features. This geographic information could be points, lines, or polygons (areas).

This table could be utilized in various ways in data analytics. For instance, the version history could be used to analyze trends over time, such as changes in land use or geographic features. The geographic information could also be used in spatial analysis, where the location, shape, and relationship between geographic features are studied. Furthermore, the unique identifier for each row could be employed in data cleaning and preprocessing, making the analytics process more efficient and reliable.
