2019 Postal Area Statistics and Postal Code Areas: Version History
The history table is a comprehensive data collection that provides a chronological record of various data points. This table, part of a larger dataset collection, houses the version history of its base table rows. It serves as a valuable tool for tracking changes over time, and can aid in a multitude of data analytics applications.
For instance, the table includes geographic information, presented using the WGS 84 coordinate reference system (longitude first, then latitude), which is key for geospatial data analytics. This data could be used to track changes in demographics, infrastructure, or the environment in specific geographic areas.
The table also uniquely identifies each row using a combination of the start date of data extraction and a row number. This makes it possible to follow the evolution of a specific data point over time. For example, a researcher could use this to track the progression of a specific demographic statistic or economic indicator.
Additionally, the table includes two special columns, 'start_date' and 'end_date', that indicate when a row was extracted from the data source and when a new version was extracted, respectively. These columns allow for the tracking of the lifecycle of each data entry, providing critical context for analysis. For instance, if the 'end_date' for a row is null, it indicates that the row is the most recent version.
The table's data is sourced from 'Tilastokeskus' (Statistics Finland) and contains a rich variety of data points. This includes information on population demographics, geographic coordinates, economic indicators, and more. This broad spectrum of data could be used in diverse applications, from studying population trends to analyzing economic development.
In summary, the history table is a robust tool for data analysis, offering a wealth of information and the ability to track changes over time. Its diverse data points and detailed version history make it a valuable resource for a range of analytical applications.
