Version History of Municipalities 2021 at 1:4,500,000 Scale

The 'table__history' is a historical data table, sourced from the 'Tilastokeskus' website in Finland. It provides a version history of its base table rows, primarily focusing on the year 2021. This table is part of the dataset collection 'tilastointialueet_kunta4500k_2021'.

The table records a variety of information, including geographical data, row versions, and municipal data. The geographical data includes geospatial coordinates and information which can be utilized for geospatial data analytics. This geographic information is presented using the WGS 84 coordinate reference system, with the axis order being longitude first, followed by latitude.

Additionally, the table contains a unique row identification system that combines the '_start_date' and '_row_number' columns. The '_start_date' records the date when the row data was extracted from the source, while the '_row_number' is the number of the row in the raw data extracted from the data source. These two columns together form a combination that uniquely identifies each row in this version history table.

Moreover, the table also tracks when a new version of the row was extracted from the source in the '_end_date' column. If the value of the column '_end_date' is null, it indicates that the row is the most recent version.

The table also includes municipal data such as the names of the municipalities in different languages.

This table can be utilized in various data analytics scenarios. For instance, an analyst could use the geospatial data to conduct a regional analysis of different municipalities, identifying patterns or trends over time. Similarly, the version history could be useful for tracking changes and updates in the data, aiding in data quality control and management. Lastly, the multilingual municipal data can facilitate international research or analysis, enabling a more inclusive and comprehensive approach.
