Version History of Municipalities 2021 (1:1 000 000)

The 'table__history' is a part of a larger dataset and serves as a history table containing the version history of its base table rows. The base table contents, denoted as 'Kunnat 2021 (1:1 000 000)', translates to 'Municipalities 2021 (1:1 000 000)' in English. This suggests that the table contains data about municipalities in Finland, as sourced from the website of 'Tilastokeskus' (Statistics Finland).

The table contains several columns, each providing unique and insightful information. For instance, there are columns that hold the row number and the dates when the row was extracted from the data source and when a new version of the row was extracted. These form a combination that uniquely identifies each row in the version history table.

Geospatial data is also represented in columns that start with 'geom_', indicating geographic coordinates using the WGS 84 coordinate reference system, with longitude first, followed by latitude. This data can be invaluable for geospatial data analytics.

Other columns contain identifiers and names of municipalities, along with the year the data represents. The column with row numbers, coupled with the start date, serve as a unique identifier for each row. If the end date is null, it means that the row is the most recent version.

This data could be used for various data analytics purposes. For instance, the history of municipalities could be analyzed over time, helping to understand trends and shifts in boundaries or names. The geospatial data could be used to create visual representations of the municipalities, enabling a geographical understanding of the data. Moreover, the table could also be used to study the frequency of updates to the data source, providing insights into the dynamics of data collection and management by Statistics Finland.
