Historical Versioning Records of Base Table Rows in Kalmar Dataset Collection

The 'cha_62fno__history' table is a history table, part of the 'kalmar' dataset collection. This history table captures the version history of its base table rows, providing a comprehensive timeline of changes over time. It records important information such as the date when a row was extracted from the data source and the date when a new version of the row was extracted. A special feature of this table is that it has two additional columns compared to its base table, which allow the tracking of the start and end dates of each row version. If an end date is not present, it indicates that the row is the most recent version.

In terms of geographic data, this table includes information transformed from the shapefile format, a common format for storing geometric location and attribute information of geographic features. These geographic features can be represented by points, lines, or polygons.

This valuable dataset is sourced from the website of Lantmäteriet (The Land Survey) in Sweden.

A few examples of how this data could be utilized in data analytics include tracking changes in area over time, analyzing the frequency and types of changes, or even predicting future changes based on historical data. Furthermore, the geographic data could be used in spatial analytics to examine patterns and trends across different geographic features. This can be particularly useful in fields such as environmental science, urban planning, or transportation logistics.
