Version History of Base Table Rows in Vastmanland Dataset
The table in question is a historical record, sourced from the Lantmäteriet's website in Sweden. This history table provides a version history of its base table rows, making it integral for understanding changes in data over time.
The table has unique identifiers for each row, which are formed by combining data from two columns: the date the row was extracted and the row number from the raw data. This combination ensures each row is distinct in this version history table.
Further, the table includes the date a new version of a row was extracted, providing a clear timeline of changes. If a row is the most recent version, this is indicated by a null value in the 'end date' column.
A distinctive aspect of this table is its geographic information, originally in shapefile format. This simple, non-topological format stores both the geometric location and attribute information of geographic features, which can be points, lines, or polygons. For this dataset, the geographic information has been transformed from the shapefile format into a final format.
Potential applications of this table in data analytics could include tracking changes in geographic features over time, analyzing patterns in data extraction, and monitoring the most recent versions of rows. The data could also be used to study the frequency or timing of updates to the base table. The combination of geographic and temporal data makes this table especially valuable for longitudinal spatial analyses.
Field Descriptions
Name | Data type | Description |
---|---|---|
_start_date | date | This column contains the date when the row was extracted from the data source. This column, in combination with the '_row_number' column, uniquely identifies each row in this history table. |
_end_date | date | This column contains the date when a new version of the row was extracted from the data source. If the value of this column is null, it means that the row is the most recent version. |
