Regional Units 2022 (1:1 000 000) - Version History

The 'table__history' holds detailed history records of its base table rows, specifically focusing on the regions in Finland as per the 2022 records sourced from the Statistics Finland (Tilastokeskus) website. The table is an integral part of a larger data collection that focuses on regional statistics. The contents of the table are presented in a structured format, catering to different categories of regional data. One of the main features of this table is its ability to track changes over time, thanks to the presence of start and end dates for each data row. This feature makes the table invaluable for temporal data analysis, enabling a deep study into the changes in region data over time.

Key elements of the table include geographic data, represented in various formats, including polygons and multipolygons. This geographic data, presented using the WGS 84 coordinate reference system (longitude first, followed by latitude), can be utilized for geospatial data analytics. It allows users to conduct detailed geographic studies, such as demographic analysis, land use planning, and environmental impact assessment.

The table also includes information about each region's name in different languages, which can be useful in multi-lingual data analysis.

Special columns that uniquely identify each row in this version history table are '_start_date' and '_row_number'. The '_start_date' indicates when the row was extracted from the source data, while the '_end_date' shows when a new version of the row was extracted. If the '_end_date' column value is null, it means that the row is the most recent version.

In conclusion, the table's rich and diverse data makes it a valuable resource for a variety of data analytics applications, especially those involving temporal and geospatial analysis.
