Version History Records of Base Table Rows in Dataset Collection

The 'blad1__history' table is a comprehensive history table that contains the version history of its base table rows. This table is a crucial part of the dataset collection 'detaljtyper_drk_xlsx'. Originating from the 'Lantmäteriet' website in Sweden, it provides valuable insights into the evolution of the data over time.

The table is organized into several columns, each having its unique significance. For instance, some columns together form a combination that uniquely identifies each row in this version history table. There are two additional columns in this table compared to its base table, which contain the start and end dates of when the row was extracted from the data source.

A null value in the 'end date' column indicates that the row is the most recent version, providing an easy way to track the most current data. In addition, the table also features a column that contains the number of the row in the raw data extracted from the data source.

This table can be instrumental for data analytics in various ways. For example, it can be used to track changes in data over time, helping to identify trends or patterns. Users can analyze how specific values have evolved, perhaps to predict future changes or to understand past behavior. Furthermore, by identifying the most recent versions of the rows, analysts can ensure they are always working with the most up-to-date data. Moreover, the unique identifiers for each row can assist in pinpointing specific data points for detailed analysis.
