Version History of Welfare Regions (1:4 500 000)

The 'table__history' is a version history table that captures the evolution of its base table over time. It's a part of the dataset collection associated with the theme of well-being areas at a 1:4 500 000 scale. This dataset collection is sourced from 'Tilastokeskus' (Statistics Finland) in Finland.

The table consists of various columns capturing different facets of the data. For instance, it includes columns that provide unique identifiers for each row, and two special columns capture the version history of each row. One column records the date when the row was extracted from the source, while another column records when a new version of the same row was extracted. This allows tracking of the most recent version of the row, which is indicated by a null value in the column capturing the end date.

Geographic information is also included in the table, contained within columns prefixed with 'geom_'. This geospatial data presents geographic coordinates using the WGS 84 coordinate reference system, with axis order longitude first, followed by latitude. The variety of geographic information available includes data types such as polygons and multipolygons, textual representation of geographic shapes, and coordinates for the geometric center of the shapes.

Additional columns capture details such as well-being area identifiers, names in different languages, and the year associated with the data. For instance, the table records the name of the well-being area in both Finnish and Swedish. The column for the year can provide temporal context for the other data in the row.

The data in this table could be valuable for various data analytics applications. For example, the version history could be used to analyze how the well-being areas have evolved over time, while the geospatial data could be used to perform geographic analytics. The data could also be used to conduct multilingual analysis as it includes names in different languages.
