sortparametre

Sortparametre is a parameter used in software to specify the ordering of items in a collection. It is commonly employed in databases, web APIs, and user interfaces to determine how results should be presented. A sortparametre typically encodes both the field to sort by and the direction of the sort (ascending or descending).

Implementation varies. In RESTful APIs, the parameter is often passed in the query string, for example sort=name to sort by the name field (ascending by default) or sort=date,-title to sort by date asc and then title desc. Some systems use separate tokens for the field and the direction, such as sort_by=name&sort_dir=asc or order=name&dir=asc. In databases, the equivalent is the ORDER BY clause, which lists sort keys and directions.

Multi-criteria sorting is common and is expressed by listing multiple keys, sometimes with combined signs, e.g., sort=name,-date means sort by name ascending, then date descending.

Best practices: validate the requested fields against a whitelist, ensure proper indexing for the sort fields, consider locale-sensitive comparisons, and handle missing or invalid values gracefully. Default sort should be deterministic to support pagination, and the sort parameter can be made optional.

Notes: 'sortparametre' is not a universal standard name; different systems choose different parameter names. Understanding its behavior is essential for matching client expectations and maintaining consistent data presentation.
