The 'table__history' is a comprehensive collection of data that encapsulates the historical developments and changes within its corresponding dataset. It is part of the 'tilastointialueet_suuralue4500k_2014' dataset collection, which is a group of interrelated data tables sourced from the 'Tilastokeskus' website based in Finland. This table provides a version history of its base table rows, recording all the iterations and updates the dataset has undergone over time.

The table features a range of columns that carry significant information. To begin with, each entry is identified uniquely by a combination of the '_start_date' and '_row_number' columns, representing the date of extraction from the source and the row's position in the raw data. The '_end_date' column indicates when a new version of the row was extracted, and a null value in this column signifies that the row is the current version.

The table also includes various 'geom_' prefixed columns that carry geographical data, which is represented using the WGS 84 coordinate reference system (longitude first, followed by latitude). This feature can be instrumental in performing geospatial data analytics.

Other columns in the table serve to provide additional context and detail about the data. For instance, columns 'name', 'namn', and 'nimi' provide names in different languages for specific regions, while 'suuralue' and 'vuosi' offer the large area identifier and the year respectively.

In terms of data analytics, this table offers rich potential. For example, the geographical information could be used to perform spatial analysis of the regions over time, exploring how they have evolved. Moreover, the version history could provide insights into changes in the dataset, enabling analysts to track data modifications and study patterns and trends.
