Database and dataset queries, using existing query features with well identified criteria. If the criteria to find the data are unclear, the [search] tag is preferred.
A query is an interaction with a database (or a comparable dataset) with the goal of finding specific data on the base of well identified criteria. Queries are made with existing query features/functions or query languages.
This topic is about:
- query specification
- query languages and functions/features
- query optimisation
- design patterns for implementing queries
Disambiguation
Use search for questions that could be related to queries, but when the criteria to be used to find the data are not completely identified.
Use jquery for questions related specifically to jQuery.
Use graph-traversal for the graph exploration and graph traversal algorithms (e.g. breadth first, depth first, A*, ...).
