Historical Version Tracking of Crime Scene Data from 2006 Shape Collection

The 'tatort2014_omr__history' table is a historical archive that holds the version history of its base table rows. This table is part of a larger dataset collection. The distinguishing feature of this table is that it contains two additional columns compared to its base table, which are used to track the start and end dates of the dataset's row versions. These dates signify when a row was extracted from the data source and when a new version of the row was obtained. If the end date value is null, it indicates that the row is the latest version. Each row in this table is uniquely identified by a combination of the start date and a row number that denotes the row's position in the raw data extracted from the source.

The table also holds geographic information, which has been transformed from the shapefile format. Shapefiles are a simple method for storing the location and attribute data of geographic features, which can be represented as points, lines, or polygons.

This vital data is sourced from the 'Lantmäteriet' website, based in Sweden.

The data in this table can be employed in a variety of data analytics purposes. For instance, the version history can be utilized to visualize and analyze trends over time, such as changes in geographic feature attributes. Additionally, the geographic data can be harnessed in spatial analytics to extract valuable insights, such as identifying patterns or anomalies in geographic distribution. Furthermore, the unique identifiers for each row can aid in ensuring data integrity and traceability in complex data operations.
